Radioactivity indicators DP-63 and DP-63-A.
Dosimeters, radiometers, roentgenometers and other similar devices.Radioactivity indicators "DP-63" and "DP-63-A" were produced presumably since 1957 and 1961. The devices have the same layout, technical data and appearance. In the modernized version of the DP-63-A, a number of new parts are used. The devices are designed to detect contamination of the area with beta and gamma-active substances and to assess the levels of gamma radiation. Measurement range from 0.1 to 50 r / gn. 1st sub-range - from 0.1 to 1.5 r / gn (button 1.5 r / gn). 2nd sub-range - from 1.5 to 50 r / gn (buttons 50 r / gn). The measurement error does not exceed 30%. It is efficient in the range from - 40 to + 50 С and humidity up to 98%. Duration of work 50 hours. The weight of the device is 750 gr .; set of 1.2 kg. The preparation time of the device is 1 ... 2 min. Powered by 2 elements 1.5-SNMTs-0.6.
