ABSTRACT:
The present invention is a device that simulates a radioactive, bacteriological and/or hazardous chemical source and a radioactivity, bacteriological and/or hazardous chemical detector, to train individuals in the correct use of a real radioactivity, bacteriological and/or hazardous chemical detector. A magnet, ultrasound emitter, or passive radio identification device (PRID) is used to simulate the hazardous material source. The PRID may include a magnet. The simulated detector includes a Hall effect device to detect the magnet when used. When the magnet is detected as a trainee moves the simulated detector close to the PRID, the simulated detector outputs a 50 ms RF burst to activate the PRID. The simulated detector may transmit the burst every 250 ms when the magnet is not used in the PRID. Once activated, the PRID waits for completion of the 50 ms pulse, and then transmits a signal that identifies the type of contamination to the simulated detector. The ultrasound emitters and magnet can be used without the need for the RF pulse to simulate a single contamination material, or the ultrasound emitters can use multiple frequencies for different materials. The ultrasound emitters may emit a modulated signal that identifies the type of contamination to the simulated detector, similar to the PRID.
