Operation Principle
PM1300 dosimeter is designed for real-time control of the radiation situation and dose exposure of the personnel while conducting radiation-hazardous works. It may be used both for autonomous work and as a part of automated personnel exposure monitoring system.
Functions
- Measurement of personal dose equivalent and personal dose equivalent rate of continuous and pulsed photon radiation
- Alarming in case preset dose or dose rate thresholds exceed
- Recording up to 10 000 events in the history
- Wireless data exchange via RF-interface and wired data exchange via USB-interface
Advantages
- Extended range of registered energies of photon radiation: from 15 keV to 20 MeV
- Long battery life: up to 3000 of hours from one power element
- Quick response to the dose rate changes
- RF-interface data exchange with personnel exposure monitoring system
- USB-interface for charging, recording and reading of data
- Possibility of remote control of personnel dose exposure while conducting radiation-hazardous works
- Can be supplied together with automated storage rack to collect, store, charge, read out and distribute dosimeters
RF interface
Dosimeter is equipped with a wireless data exchange module which allows automated registration of the personnel in exposure monitoring system and issuing personal radiological work permits; simultaneous transmission of measurement results to the personnel exposure monitoring system from several dosimeters; remote control of the access, movement, location and duty hours of personnel in the restricted areas under issued radiological work permits; integration to automatic access control systems.
The reader may be located autonomously in different zones of the controlled areas and simultaneously receive data from several dosimeters in the acquisition range and also may be built in different gadgets like turn gates, info desks, etc.
Automated storage rack
Dosimeter maintains its operation with automated storage rack for the group dosimeter storage which enables storing and controlling the access to the set of personal dosimeters by means of authorization in facial recognition system or entering access code, remote data transmission and adjusting parameters of the instruments, automated registering in exposure monitoring system and issuing personal radiological work permits, battery recharging.
