Personal Dosimeters AT3509, AT3509A, AT3509B and AT3509C
Pocket-size wide-range intelligent devices, ideally matching accuracy, functionality, user friendliness, reliability and price.
Dosimeter with reader, which is connected to PC, and software suite make
an efficient automatic system for staff radiation exposure monitoring.
Operating principle
Primary dosimeter function is to measure Hp(10), Hp(0.07) individual
dose equivalent, and the secondary one is to measure Hp(10), Hp(0.07)
dose rate of continuous X-ray and gamma radiation.
Dosimeters provide dose range measurement in 7.5-order range and have individual sound and LED alarm function.
Microprocessor operation mode management, data processing, display on TFT screen and self-check function.
Accumulated dose data and dose accumulation history is saved in non-volatile memory when the device is powered off.
Application
- Radiation protective measures in case of nuclear disasters
- Roentgenology
- Therapeutic radiology
- Nuclear medicine
- Electronics (Ion implanters)
- Accelerating installations
- Nuclear research activities
- X-ray Crystallography and X-ray Fluorescence Spectroscopy, electronic microscopy
Features
- Silicone planar detector
- Zero intrinsic background
- Simultaneous measurement of visceral radiation exposure Hp(10) and skin radiation exposure Hp(0.07) - AT3509B and AT3509C in wide range of dose rates
- Compensating filter and electrical energy dependence correction
- Resistance to impacts and vibration, dust-and-moisture-proof, tolerance to electromagnetic interference
- Repeating impact protection (so called "Microphone effect")
- Parameter self-check
- Can be integrated into a system or used separately
- Low weight and small size
- Calibrated with water phantom ISO 30x30x15 cm
- Dosimeter-to-PC communication via IR-transmitter in reader
