MODEL : B-500
Description
Radax Radiation Detector B-500 commonly called Bleeper B-500 is a popular in Gamma & X-Ray Radiation Detector. Its small in size and weight and can be easily worn by the Radiography Technician when carrying out Radiographic work. Bleeper B-500 is fitted with Geiger Muller detector (GM Tube) which contains an ionizing gas when B-500 taken near the X-Ray and Gamma Ray source. The gas in the detector gets ionized and gives a signal.
The Signal is in the form of chirping sound. The chirps are repeated frequently as B-500 goes waver the radiation source. When going near, the radiation field becomes stronger, the chirping frequently becomes fast such as Beep, Beap, Beap…… When B-500 goes closer to radiation source, the chirping becomes fast and sounds like a Vistle. Sometime the chirping sound not high and operator cannot clearly hear it. In such cases there is an additional Buzzer/Vibration is fitted in B-500. The Buzzer is similar to one fitted in the Mobile phone. So even if B-500 is in the pocket of the operator, the Buzzer or Vibrator shall “Alert”, the technician about high radiation.
