The programme NukVer is used for management and ba­lancing of radiopharmaceuticals used in a nuclear-medical institute.
The overview of current orders, the stock status for freely defi­nable periods, the applied activities and the disposal of radi­oactive waste can be viewed. The current stock management takes into account the half-life.
Radiopharmaceuticals can be ordered directly from the pro­gramme. Additionally, the programme creates the required data for the authorising agency.

The nuclide management programme can be extended to a comprehensive radiopharmaceutical management system.

ISOMED 200

The well-counter ISOMED 200 is a specially developed, f.l-controller-based well-counter for routine use in nuclear­medical practices.

- nuclide (energy) window with fixed setting
- measuring value display in cps, cpm or as a time-based count rate
- simple operation by means of touch screen
- spectrum display as part of the integrated quality check
- shielded Nal-scintillation detector
- requires little space

The PC-based well-counter ISOMED 2100 is a standard measuring system for clinical use. Equipped with a fast mul­ti-channel analyser and a high-sensitive Nal-scintillation de­tector, the digital measuring value and the energy spectrum are displayed on line during measurement. An automatic dead time and background correction can be activated. The measuring values can be stored and printed. Measuring va­lue tables can be displayed graphically (as a function of the time) and the energy spectra can be evaluated by means of spectroscopy.
A menu to carry out the quality checks according to DI N 6855 is integrated in the standard software.
The PC-based well-counter ISOMED 2100 can run on a cen­tral PC-system in combination with e.g. a dose calibrator. In this way you can reduce costs and required space.

The Probe Counter ISOMED 2101 is an in vitro-counter for general applications in nuclear medicine and study. It is offe­red separately or as a component of combined counters, to­gether with other components and medical software. Typical fields of application are: medical function checks, ILP-moni­toring and spectroscopy evaluations. Preferably Nal-probes are used as detectors.

The Thyroid Counter ISOMED 2162 is a universal in vitro­counter, especially for diagnostics and therapy of the thyroid. The measuring system consists of a powerful PC-system with integrated MED multi-channel analyser and a stand system accommodating the shielded Nal-scintillation detector. The heart of the measuring system is the user-specific software Upt2000 (see description). Apart from the field of applicati­on thyroid, the measuring system can also be used for kine­tic function analyses, incorporation monitoring of personnel working in the therapy field and for the leakage check of the Isolated Extremity Perfusion (ILP).

Many accessories like e.g. collimators, absorbers, thyroid phantoms and test sources complete the thyroid counter.

Thyroid programme Upt2000
The thyroid programme Upt2000 is used for diagnostics and therapy of the thyroid. From a maximum of 30 uptakes for a patient, the programme calculates the parameters effective half-life and maximum storage. With these parameters, the activity for the dose planning of the radiotherapy and/or the effective focal dose during therapy.
Together with the Probe Counter ISOMED 2101, the thyroid programme is generally part of the Thyroid Counter ISOMED 2162 or of combined counters, with online processing of the measured count rates. Together with the patient data, the examination results can be stored in a database, printed as a protocol and transmitted to a network.

Essential characteristics are
- calibration for 1-123, 1-131 and Tc-99m under maximum 8 different calibration conditions (distance, absorber ... ) for diagnostics and therapy
- manual input of the thyroid mass or calculation from the scintigraphy and/or sonography data
uptake determination from background and thyroid activity or from thyroid and whole body activity
- determination of the therapy activity and focal dose also from an uptake
graphic display of the uptake curve as a function of the time
calculation of the required period as an in-patient and its earliest possible release. Limit values can be chosen from activity, dose rate and yearly dose.
- post-applications can be taken into account possibility for self-measuring of patients. The patient identification takes place by means of a transponder. - network connection between several thyroid counters.
In this way e.g. a transmission between diagnostics and the­rapy wards is possible.
Our software fulfils the current regulations, standards and directions. The software was created in intensive cooperation with our customers and is based on their experiences.

According to the German Radiation Protection Ordinance and the "Directive for Physical Radiation Protection Control", a frequent incorporation check to calculate the partial body dose of the thyroid has to be performed on all employees of a radioiodine therapy ward. The monitoring interval for 1-131 is 2 weeks.
Normally, the incorporation measurements are carried out at a licensed, external measuring institute. Due to the distance, is time consuming, a high strain on the employees and also on organising the sequence of work in the hospital. Addi­tionally to the time and organising efforts and the external incorporation monitoring also requires rather high costs.
As an alternative to the external monitoring, a frequent measurement of the partial body dose on own responsibility is possible and has been proved in practice with the incorpo­ration monitor ISOMED 2163.

The Incorporation Counter ISOMED 2163 consists of:
- PC-based Probe Counter ISOMED 2101 with integrated MED multi-channel analyser
- Nal-scintillation probe 3 x 3" with shielding and collimator
- stand or special chair (picture)
- software Ink2000

Incorporation programme Ink2000
The incorporation programme Ink2000 is meant for routine incorporation measurement. The measuring system measu­res the count rates of the thyroid and calculates the thyroid activity. In addition to the activity, the accumulated dose over a definable time period is calculated too. Measurement and evaluation are possible for 1-123,1-125 and 1-131. Together with personnel data, the examination results and evaluati­ons can be stored in a database, printed as a protocol and transmitted via a network. They fulfil the requirements of the governmental institutes.
You can choose between two monitoring procedures.
In case of the usual procedure up to now, with the typical measuring intervals of 2 weeks (for 1-131), the time moment of incorporation is supposed to be in the middle of the inter­val. The single doses are calculated by means of integration till the end of life. The required detection limit (is calculated and displayed) may not be exceeded in this case.

In case of the individual procedure, the incorporation measu­rements take place in shorter intervals, in general daily. The single doses are calculated by means of integration till the next measurement. The continuous recording of the activity as a function of the time and the small statistic error allow the recognition of 3% of the allowed yearly dose limit value in spite of exceeding the detection limit. The allowed measuring error makes it possible to use smaller shielding and shorter measuring times.

Essential characteristics are:
- online processing of the measured count rates from Probe Counter ISOMED 2101.
- taking into account the individual thyroid mass and the effective half-life
- taking into account the rest activity of the previous incorporation measurement
- calculation of the partial body dose and effective dose over a definable time period
- graphic display of the activity course during a calendar year and of the current energy spectrum
- listing of the measured thyroid activities and the calculated dose values of all employees over a definable time period
- listing of the performed checks of each employee
- log-on of the person to be measured by means of transponder or chip card
- possibility of obligatory contamination check by means of HFC-monitor before incorporation measurement
- transmission of patient data and examination results via standard network or GDT-interface
- menus for data storage and archiving
- protection for manipulations and wrong operations by several menu levels protected by passwords

The Waste Water Counter ISOMED 2151 is preferably meant for activity determination of single samples from waste wa­ter decay containers of nuclear-medical institutes. Both 1-131 and e.g. F-18, Sr-89, In-ll1, 1-125, Tc-99m as well as TI-201 can be measured as single nuclides and nuclide mixtures. The samples taken from the waste water containers are put into special measuring containers (ll-Marinelli beaker or Ro­ediger-cartridges). The measuring value is displayed in Bq/I. In this way, the limit value prescribed by official regulations (5 Bq/I for 1-131) can be reliably proved. Additionally, the time moment when the specific activity of the waste water contai­ner falls below the limit value prescribed by official regulati­ons is calculated and displayed. The measuring values can be assigned to the according waste water containers and can be stored together with the energy spectra. The printed protocol contains not only the measuring value tables, but also the last energy spectrum and the user logo.
The Waste Water Counter works on PC-basis as a Windows application with a fast multi-channel analyser and has an automatic dead time and background correction. The used menu technique guarantees a simple operation. The availab­le energy calibration allows a simple setting of the required nuclide-specific isotope windows. The current energy spect­rum is displayed in a control window and informs the user continuously about the measuring function. Network integra­tion is possible.
A 3" x 3" Nal-scintillation probe is used as detector. It is placed in a 50 mm lead shielding. The measuring beaker is inserted from the top.

The Waste Water Counter ISOMED 2153 is meant for y-spec­trometric in line activity measurement of 1-131 from waste water of nuclear-medical institutes, which is stored in decay containers.
The Nal-scintillation probes which are used as a detector are positioned in an inner pipe inthe middle of the storage tank. Up to 8 containers can be monitored simultaneously. The measuring value is digitally displayed in Bq/1.
At the same time, the time moment when the specific acti­vity of the waste water container falls below the limit value prescribed by official regulations and the waste water can be pumped into the public canalisation is calculated.
A graph shows the required decay time for each container till it can be emptied, together with the according date.
In the automatic mode, the activity of the single containers is automatically measured and stored one by one. Measuring times and measuring distances can be defined individually. The measuring tables assigned to the containers can be dis­played as a time diagram. Protocol print as well as network integration is possible. This makes e.g. the transmission and display of the measuring values in a measuring overview pos­sible. The stored energy spectra can be evaluated by means of spectroscopy.

In the revised German Radiation Protection Ordinance (StrISchV), the release of radioactive waste is comprehensively regulated. The "unrestricted release" in this case is especially important for the disposal of temporary stored, short-life nu­clear medicine radio-nuclides. This waste can be disposed as normal waste, if they fall below the nuclide-specific release limit value of specific activity listed in the StrlSchV.

With the release counter FMS, radioactive waste containers can be measured in a reproducible way and the measuring results can be documented according to the license. Carrying out release measurements significantly reduces the disposal costs which come up.

- protocolling of entrance and exit measurements according to the license requirements
- automatic consideration of the waste weight via integrated balance with serial interface.
Calculation of specific activity in Bq/g
- calculation of storage time / renewed submission time
- exit measurement after n-half-lifes or after calculated falling below the release limit value
- comprehensive data management programme with stock accounting, incl. data selection (variable filter functions)
- print of a disposal protocol for documentation and to present to a governmental institute for release to dispose

In a nuclear-medical hospital not only radioactive or radioac­tive contaminated waste comes up, but logically also conven­tional waste. In case of collection, treatment and disposal of waste in a nuclear-medical institute, the success in separating radioactive from conventional waste depends on the precisi­on of each employee / patient. Even the smallest quantities of radioactive waste in conventional waste make it to radioactive waste.
With the waste control monitor you can assure, that during waste disposal no radioactive and conventional waste are ex­changed or mixed.

Performance features:
- U-shaped detector configuration of 4 high-sensitive
Nal-scintillation detectors
- housing open at the front for easy loading
- integrated light barrier for automatic measuring start
- very easy to use check system
- can also be used as a clothing monitor

Anyone who works with unsealed radioactive material can get contaminated. To check the personnel working in the con­trol area, a stationary HFC-contamination monitor is placed at the exit, according to the German Radiation Protection or­dinance (§ 44 StrISchV). In appendix Ill, Tab. 1, column 4, the limit values of surface contamination are defined nuclide­specifically.

An essential advantage of the portable contamination mo­nitor CoMo-170 is the innovative detector technology, which does not use any gas-flow or gas-filled detectors at all. A thin­layer plastic scintillation detector is used.

This type of detector is both, a-, ~- and y-sensitive. In case of mechanical damage of the detector foil, the detector does not have to be repaired by the manufacturer, unlike a xenon de­tector, which is time consuming and costly. Instead, the repair is simple, cheap can be performed by the user.

PC-based measuring network for online patient monitoring of radio-iodine therapy wards

Because of radiation protection regulations it is only allowed to perform the 1-131 therapy under stationary conditions. The release of a patient from stationary treatment after applicati­on of open radioactive materials and/or sources in the body is only allowed, if the dose rate on the day of release on 2 m distance doesn't exceed 3.5 ~Sv/h. This corresponds to a rest activity of approx. 250 MBq.

The PADOS system makes it possible to measure and register the current activity and/or the dose rate of the resting patient periodically. For measurement, a detector collimated for the area is mounted overthe bed. A Nal-scintillation probe is used as detector. Via a serial interface (RS 485) the detectors are connected to the central PC-system. The cables are mounted from one detector to the next ... up to the PC-system.

The measurement data are analysed and stored by the PC­system. Only constant measuring intervals are used for moni­toring. Based on the periodically registered data, the system software calculates the expected moment of falling below the limit value as date for the patient's release. In this way, an optimized bed planning for the therapy ward is possible.

PC-based single place system for manual, self-responsive patient monitoring on a radio-iodine therapy ward

If the installation of a measuring network including cable in­stallation requires too much work or is impossible due to the building's construction, the PADOS 11 system makes a directly comparable monitoring possible.

The PADOS II system has been developed for manual, self­responsive measurement by the patient. For this purpose, the measuring system is installed at an appropriate, central loca­tion on the therapy ward. After identification by means of a bed-based transponder system, the patient measure themsel­ves independently 1 - 3 times per day here. The mechanical construction with a motor-adjustable chin holder guarantees a stable measuring geometry and a reproducible measure­ment. The exact measuring position and the observance of the required measuring time is checked by a light barrier in­tegrated in the chin holder.

The measuring system consists of a shielded counter tube for measurement of the thyroid activity and a second, energy­compensated counter tube for measurement of the total body dose based on 1 m distance. The PC-based measuring sys­tem works with a modified PADOS software.

According to the German Radiation Protection Ordinance (StrlSchY §§ 40, 41), the body dose of persons has to be de­termined. Upon request, the person to be monitored has to be provided with a dosimeter to be able to measure the per­sonal dose at any time. For pregnant women, the radiation exposure at work has to be determined every week.

Nowadays, for dose monitoring, modern powerful electronic dosimeters with easy to read LCD-display and definable dose and dose rate alarm thresholds are available.
