Technical characteristics. Impressions of operation

DP-5 - undoubtedlythe most mass Soviet military radiometer - roentgenmeter (ionometer). It was developed in 50th years of the last century and, in various modifications, has successfully lived up to now. The version with a letter “A” – was naturally the very first. Then would follow, “Б”, “B”, “M” -(medical) and the latest “BБ”.

Years wentby. On change to valves transistors, then microcircuits, then microcontrollers have come... And DP-5 remained such as was. Only small cosmetic changes. Have slightly changed the scheme, in the version "B" have removed the gammaradiation detector built in the case, and the case began to made of more modern and strong plastic, have rearranged control strontium-yttrium source from the device case on the case of the block of the detector. Have changed the tableton a cover inside (have entered there more sparing "norm of contamination"). Thats actually was all the innovations.

This is the top model of Lviv’s Scientific and Production Private Enterprise (SPPE) "Sparing-Vist-Center". The device is focused on professional users, much can and costs a lot. It is recommended by the manufacturer to use in system of the radiating control of Ukraine, including: in divisions of radiochemical investigation of a civil defence, in armed forces, in services of a radiation control of atomic engineering, in medicine, in the nuclear physics.

Many people already had time to named MKS-U: "the reincarnation of legendary veteran the DP-5". During the given review I will try to find out is it true.

I was looked at Lvover’s from "Sparing-whist" working with delight for a long time, but purchase turning point, there was just one unique pinning of my old radiometer "Pripyat" in one of "dirty" places of the Chornobyl Zone. I remember, how we with Evgenie Samoilov in thoughtfulness contemplated the empty screen of "Pripyat" with “one” in the senior category (pinning of the device), listened to hysterical trills of its sound signalling device and with a clever kind, on frequency of squeal and speed of leaving in pinning, gave out various figures of a prospective gamma background :).

How many there was? I do not know. A limit of measurement by EDR (exposition dose rate) at radiometer "Pripyat" - 20 mR/h. All that I can tell definitely - there was more than 20 mR/h.

Radiometer "Pripyat" – the device "Legend", the device - "History".

It is developed more then 20 years ago at the Korolev Kyiv Factory (now NPO (scientific production association) "Meridian"). The best for its time and the most popular consumer radiometer, since 90th years of the last century and till today. It let out at many factories (personally, I saw not less than three variants of this device). For example at the Lviv’s "Pripyat" the case has red color. 

Radiometer "Pripyat" - the unique device a long-liver. What else electronic device can be boast of such age?

And so once again I will repeat, for its time it was High-End the Soviet consumer radiometers. Better to say, there was "Pripyat" and there were all the others.
