Nuclear radiation detection system

Abstract

The invention discloses a nuclear radiation detection system comprising a control circuit board, wherein the control circuit board is provided with a detection drive circuit, a data collection and process module, a display and alarm module, a keys operation panel and a power module; the power module has a given voltage; the key device of the data collection and process module is a singlechip which is electrically connected with the display and alarm module, the keys operation panel and the power module respectively; the detection drive circuit is provided with a GM counter tube; a boost module is connected between the GM counter tube and the singlechip and comprises a 5V boosted circuit and a counter tube drive boosted circuit; and the control circuit board is also provided with a low-voltage protection drive circuit. Due to the combination of the GM counter tube and the singlechip, the nuclear radiation detection system improves measurement range and precision, is capable of automatically converting range and adjusting response time, realizes low measurement environment, is applicable to most work situations and is small in volume and safe in use.

Description

technical field [0001] The invention relates to a radiation measurement technology, in particular to a nuclear radiation detection system. Background technique [0002] The current radiation detectors usually have the problems of large size, inconvenient to carry, low sensitivity, and single function. Many radiation exposure accidents are caused by the lack of suitable systems on site or failure of staff to wear alarm detectors according to regulations. , and the radiometers currently on the market generally include the following two types: one is palm type, which is similar in appearance to ordinary semiconductor radios, and all components are installed in the casing. Although the sensitivity can reach the drug measured, the volume is relatively large , not easy to carry around. When measuring a radioactive target, you must hold the entire detector with your hand to make the detection element close to the detection target for testing. It is inconvenient to detect areas in s...

[0002] The current radiation detectors usually have the problems of large size, inconvenient to carry, low sensitivity, and single function. Many radiation exposure accidents are caused by the lack of suitable systems on site or failure of staff to wear alarm detectors according to regulations. , and the radiometers currently on the market generally include the following two types: one is palm type, which is similar in appearance to ordinary semiconductor radios, and all components are installed in the casing. Although the sensitivity can reach the drug measured, the volume is relatively large , not easy to carry around. When measuring a radioactive target, you must hold the entire detector with your hand to make the detection element close to the detection target for testing. It is inconvenient to detect areas in special occasions. The other is wearable, generally equipped with a hanger In the waist, the volume is relatively small, and all the components are also installed in the shell, but due to the limitation of the volume, the detection device can only be small, so the detection range is not large enough, the sensitivity is not high enough, and it cannot meet a certain radiation range. occasion
