COLD WAR ERA - CIVIL - MILITARY - PEN TYPE PERSONAL RADIATION DOSIMETER DL-M3

Description: *** COLD WAR ERA - CIVIL - MILITARY - PEN TYPE PERSONAL RADIATION DOSIMETER DL-M3 *** Up for sale, COLD WAR ERA - CIVIL - MILITARY - PEN TYPE PERSONAL RADIATION DOSIMETER model DL-M3ORIGINAL NOT USED ARMY PERSONAL RADIATION MEASURER DL-M3 MADE IN 1980's : The ampule dosimeter is a chemical under the influence of gamma and neutron particle changes color in proportion to the dose. This item called a diagnostic dosimeter because the radiation of an objective measure of the level of the individual. The principle of measuring dose irradiation (besides ampoules hem. Mixture) can be semiconductor, based on sensitive crystals. Standard for gamma and neutron radiation dosimetry is proposed based on the liquid chemical system containing chlorobenzene, ethanol and the colour indicator dissolve in 2,2,4-trimethylpentane. Commercial personal dosimeters DL-M3(M4) based on this system are characterized by statistical examination of the visual readout method and of the obtained dosimetry results. It is concluded that this simple method can give accuracy and precision required for dosimetric standardization of radiation therapy, and that it can be used as an accurate transfer dosimeter in neutron dosimetry. Of special advantage is the possibility of accurate dosimetry performed by persons not professional in the field. WHEN IS RADIATION CONTAMINATION CHANGE COLOR TO ORANGE ... RED , DEPENDING ON THE STRENGTH OF RADIATION. FOR PRECISE READ YOU MUST HAVE A CDL-M3 READER. Dosimeter reader housed in waterproof plastic carrying box. (There are small signs of standing on the housing dosimeter ) Dosimeter is like a pencil, and the dimensions are such, each dosimeter has a unique serial number and no battery required . Measure 0--1500 RAD (0-15Gy) Error radiation contamination gamma rays FOR 4.5 Gy radiation is 2% -3 % Working temeprature is -30c to +55 celsius Used by Yugoslavian and Serbian army. Made by Institut Rudjer Bokskovic - Zagreb - Yugoslavia for military and civil use NOS - MILITARY SURPLUS
