Electronic Personal Dosimeters
PERSONAL DOSIMETERS AT3509, AT3509A, AT3509B AND AT3509C
Modern wide-range accurate microprocessor instruments to control personal dose equivalent Hp(10) and Hp(0.07) and dose rate of continuous and short-term x-ray and gamma radiation. Together with the reader connected to PC the dosimeter can be a part of automated monitoring system of staff dose burden.
Features: - Continuous x-ray and gamma radiaion dose H*(10) equivalent
- Continuous x-ray and gamma radiaion dose H*(10) equivalent rate
- Continuous x-ray and gamma radiaion dose H*(0.07) equivalent (only AT3509B and AT3509C)
- Continuous x-ray and gamma radiaion dose H*(0.07) equivalent rate (only AT3509B and AT3509C)
- Silicon flat detector
- No propoer background
- Simultaneous dose burden measuring on the inward parts of the body Hp(10), skin and mucous membranes Hp(0.07) - AT3509B and AT3509C
- Compensative filter and electronic energy response correction by 4-channel analog processor Download a leaflet (243 kb)
- Proof against the microphonic effect Download Acrobat Reader
- Self-testing mode
- Possibility to use separately or in a system
Application: - Radiology
- Radiotherapy
- Nuclear medicine
- Cosmic dosimetry
- Accelerators
- Nuclear research
- X-ray and fluorescent analysis
- Electronic equipment
The dosimeters are intended to measure personal dose equivalent and dose equivalent rate x-ray and gamma radiation. They measure dose rate in a wide range and have separate audible and visual alarm. Microprocessor processing and proper background detection ensure high accuracy of dose measurement within the wide dose rate measuring range. The microprocessor controls operation modes over, calculates, outputs data on a backlit LCD and performs self-testing. The nonvolatile memory keeps the accumulated dose and its accumulation history when the dosimeter is off. The dosimeter is calibrated on a water phantom of 30 x 30 x 15 cm according to the ISO4037-3 International standard requirements. The instruments are watertight, electromagnetic and shock proof (fall from 1.5 m).
The dosimeter can operate singly or in a dosimetry monitoring system: dosimeter - reader - PC. The dosimeter connects to the reader via IR channel, and the reader connects to PC via RS232. The dosimeter software is intended to:
- Read/setup personal and serial dosimeter numbers;
- Change dose and dose rate
thresholds;
- Disable/enable to change dosimeter thresholds by the dosimeter button;
- Change the dose accumulation interval in the range from 1 to 255 min and evaluate accumulated dose for each time interval within a work shift;
- Save automatically up to 800 dose values in the nonvolatile memory accumulated for the selected accumulation interval;
- Reset accumulated dose;
- Disable/enable to reset accumulated dose by the dosimeter button;
- Save automatically data in the data base and print them.
The operation modes are "Dose ", "Dose rate ", "Economical", "Menu", "Reset dose", "Dose threshold", "Dose rate threshold" and "Data exchange with PC".
Additional informations:
Complete set: personal dosimeter, batteries, chain with a clamp, plastic boxes for easy decontamination, Manual and package.
The reader and applied software are options and they are supplied on additional order.
All modifications of the personal dosimeter AT3509 have pattern approval certificates of Republic of Belarus, Russian Federation, Kazakhstan and Lithuania, and modifications AT3509, AT3509A have pattern approval certificate of Ukraine.
The comply with IEC 61526 International standard requirements. They also conform with the 89/33/EEC Directive complying with EN 55022: B:1998 and EN 55024 B: 1998 standard requirements.
