Development of Radiac Set AN/TDQ-2 for Detection of Pulsed X-Radiation from High Powered Electronic Equipment

摘要

A remote area monitor was developed for the purpose of detecting and measuring steady or pulsed x-radiation emission from high powered electronic equipment associated with radar installations. The system consists of six detectors connected to a central console by 250' cables. Each detector consists of a two foot square plastic scintillator coupled to a plastic light pipe which converges to a single photomultiplier, an internal calibration source and an amplifier. RF shielding is also provided. The central console utilizes six interchangeable modules with five decade logarithmic scales to indicate the radiation dose-rate from 1 milliroentgen/hour to 100 roentgen/hour. A push button switch is incorporated for each channel to check the calibration of the detector. In addition, an alarm system in the console provides both visual and audible signals when any one detector exceeds a pre-set radiation level. A fail-safe circuit was designed which indicates failure of detector operation by means of a bright light mounted on each module. The entire system was designed to operate on its own emergency power supply during power failure of up to 50 hours. (Author)
