Soviet Union DKP-50 DOSIMETER RADIATION DETECTOR PEN PERSONAL GEIGER COUNTER

Description: Soviet Union DKP-50 DOSIMETER RADIATION DETECTOR PEN PERSONAL GEIGER COUNTER made in the USSR. Personally, I did not see any traces of use, the device is in very good condition (therefore, I think that it was not used at all, so please determine the condition from the photo). The DKP-50 dosimeter is used to determine the individual, total gamma radiation dose in the range from 0 to 50 x-rays at radiation intensity from 0.5 to 200 R / h. It has the shape of an eternal pen and is worn in your pocket. The cylindrical housing of the dosimeter is made of dur-aluminum. Inside the dosimeter hull, the measuring microscope consists of an eyepiece, lens and scale. The microscope allows up to 45 times magnification. The dosimeter scale has 25 divisions, the plot value is 2R. The inside of the dosimeter on the loading side is sealed with a rubber ring and nut. They are protected against atmospheric influences and dirt by a metal cap with a glass in the bottom. The cap must be unscrewed before each loading of the dosimeter. The DKP-50 dosimeters should be handled with care, as impacts and shocks may damage the device. The dose is read on the dosimeter scale. The dosimeter is charged on the PZ-65 loading desk or on the loading and measuring desk of the DP-23P sets. In addition, the DKP-50 can be charged in the X-ray radiograph DP-66M socket which with an internal battery in the form of two 1.5V R20 cells provides 1000 dosimeters charge and work during 50 hours. 25 pieces of DKP-50 dosimeters consisted of a set of KD-65 dosimeters placed in a wooden box and 50 pieces of DKP-50 in a set of dosimeters DP-23P. Dosimeters of this type can be measured in the temperature range from -20 to +50 degrees Celsius while they do not lose efficiency even at -40. Dosimeters DKP-50 operate at a relative humidity of air up to 95% +/- 3%. In addition, the construction of DKP-50 dosimeters allows them to be in water at a depth of 0.5 m for 30 minutes. The leakage capacity of dosimeters is: -2 plots (4R) within 24 hours under normal atmospheric conditions and within 4 hours at -20 +/- 2 degrees Celsius -3.5 plots (7R) within 24 hours at a temperature of +50 degrees Celsius +/- 2 degrees and within 48 hours at a relative humidity of 95% +/- 3% and at a temperature of +20 degrees Celsius +/- 5 degrees . The dose measurement error can reach +/- 15% of the total scale value. The weight of the DKP-50 dosimeter is approximately 50 g and its dimensions 135x12 mm. Until July 1964, DKP-50 dosimeters with magnetic charging contact were produced, after July 1964 DKP-50 dosimeters with mechanical charging contact were produced, which means that only dosimeters with mechanical contact can be charged in the PZ-65 loading panel. In contrast, dosimeters with magnetic contact have caps in the shape of a cone with mechanical contact in the shape of a ring, in addition, the central electrode (visible through the sight glass of the cap) in dosimeters with mechanical contact is made of brass and with an incision to adjust with a screwdriver, this version can be viewed on art photos from my collection. Dosimeters DKP-50 are stored in wooden boxes charged. Dosimeters are recharged before being handed over to persons entering the contaminated area. https://www.youtube.com/watch?v=Ro0ZmHnj-10. For a better assessment, see the photo, consider your choice before buying, write for more information, I will be glad to answer. By purchasing this lot, you get a piece of the history of the once great superpower of the USSR, which no longer exists, given the subject is no longer produced, every day they become less and less. There are other items of the former USSR on my auction, look, choose. I remind you that when buying several lots, you can significantly save on shipping (I send lots together). In the photo, I tried to convey the condition of the item as best as possible, if you have additional questions, please ask them before the completion of the transaction, I will be happy to answer them. ATTENTION!!! Perhaps there is no information in the announcement, so I clarify, I send lots around the world, except for Russia, Belarus (a principled position). The shipping cost indicated in the ad is valid worldwide. Sending is possible worldwide, except for the indicated countries, please ask for any relevant details. When buying several lots, we combine them into one package, if when buying several lots, funds are debited from your account for each lot for delivery, I issue a refund of your money that exceeds the shipping limit. You can also tell me about the lots that you want to purchase, I can combine them into one lot with an indication of the total amount of goods and shipping, so it will be profitable. I accept returns, sending the return at the expense of the sender. Please note that I am not subject to taxes and customs duties set by the country of the recipient (if such rules are set by your country), such taxes are paid by the buyer. Due to the situation in Ukraine, as well as due to interruptions in the work of the delivery service, the parcel may sometimes be delayed, please treat this with understanding.
