NEW Universal Charger For Dosimeter ID-1 DKP-50A Radiometer Counter Detector Made in USSR Original Universal Charger For Soviet Military USSR Army Personal Dosimeters: ID-1 DKP-50A Dosimeter / Radiometer / Geiger Counter / Radiation Detector Universal charger can charge or recharge individual dosimeters like ID-1 and DKP 50А Dosimeters ID-1 and DKP 50А were dosimeters produced for the Soviet's Army during the cold war era. Radiometers ID-1 and DKP 50А indicate amount of radioactivity absorbed by the body. Each soldier was equipped in this device in case of nuclear conflict. Radiation detector ID-1 was worn attached to pocket or belt by means of the retaining clip. A scale has range of 0-500 Rad. The dosimeter ID-1 allow one to estimate absorbed dose (Rads) of gamma radiation up to 500 Rad. Radiation detector DKP-50A was worn attached to pocket or belt by means of the retaining clip. A scale has range of 0-50R (R = Roentgen, a legacy unit of exposure of X-rays and gamma rays). 500R in 5h is usually lethal. Dosimeters are useful for estimating your absorbed radiation dose in a radioactive environment. For example, after a nuclear accident a dosimeter allows you to determine (roughly) the amount of radiation absorbed. These ID-1 and DKP 50А dosimeters measure radiation in Rads/R, which is the absorbed dose. The equivalent dose (Rem) is equal to the Rads for gamma radiation, which is what this unit measures. Rem dose helps us determine radiation effects on the body. The modern unit for radiation is the Gray (Gy) for absorbed dose and the Sievert (Sv) for equivalent dose. Conveniently, 1 Gy is equivalent to 100 Rad and 1 Sv is equivalent to 100 Rem. So these dosimeters measure from 0 to 500 Rad (0 to 5 Gy). The ID-1 dosimeter is designed to monitor the accumulated dose of radiation that an individual soldier has been exposed to. Like all dosimeters, the ID-1 is a simple electrometer. Inside the device there are two electrodes which are charged by means of an external electrical source. Both of the electrodes within the device have the same charge and repel each other. The charge on the electrodes is neutralized when ionizing radiation passes between the electrodes and the casing. This reduction in the charge causes an electrode to move away from its start point, this movement can be seen against a scale when the user looks through the device. The DKP-50A dosimeter is designed to monitor the accumulated dose of radiation that an individual soldier has been exposed to. It replaced the DKP-50 dosimeter that was used in the 1950's. Like all dosimeters, the DKP-50A is a simple electrometer. Inside the device there are two electrodes which are charged by means of an external electrical source. Both of the electrodes within the device have the same charge and repel each other. The charge on the electrodes is neutralized when ionizing radiation passes between the electrodes and the casing. This reduction in the charge causes an electrode to move away from its start point, this movement can be seen against a scale when the user looks through the device. Both devices based on ionizing chamber that changes radioactivity radiation to an electric current, current discharges a capacitor that is also used as a power source. The devices measure discharge of a capacitor over time. This is done by using a wire that accordingly changes its position and optic unit to make those results available for the operator Parcel included only 1pcs ZD-6 Universal charger for ID-1 and DKP 50A dosimeters. Dosimeters not included. You can buy it separately in my store.
