Brief introduction: Rdm-1 wound radiation meter USES sensitive semiconductor detector, with probe cover can be used for low level alpha radiation contamination detection on the surface of human wounds, but also can measure the dose rate of external radiation gamma after human wounds are contaminated by nuclides. It has good detection efficiency, high reliability and convenient operation characteristics. The instrument is controlled by a single chip microcomputer, which can continuously record and store the measurement data and obtain it by computer communication. The equipment can be used in many fields such as nuclear emergency response (as a complementary product of military nuclear emergency response box), nuclear medicine, nuclear power plants, nuclear fuel production, transportation, storage and commodity inspection. The control functions of the instrument include: background measurement timing selection, pollution measurement timing selection, alarm threshold setting, data communication selection, sound and light alarm, etc. Main technical indicators: 1.
