A Sensitivity Amplifier for Nuclear Radiation Detection

Abstract

The invention provides a nuclear radiation detection sensitivity amplifier which can be applied to a CCD / CMOS camera, which belongs to the technical field of nuclear radiation detection. The amplifier comprises a high density amplifier main body, a light shielding cover, a fixation clip and a photoprotection sealing gasket. The high density amplifier main body is used for causing ray which comes into a CCD / CMOS sensor and cannot be detected around the sensor to generate physical interaction with the high density amplifier main body to generate scattering particles and secondary particles and enabling the scattering particles and the secondary particles to come in to the CCD / CMOS sensor at certain probability. The light shielding cover and the photoprotection sealing gasket are respectively located at the upper opening and the bottom of the high density amplifier main body to prevent visible light from coming into the camera. The detachable fixation clip is used to fix the nuclear radiation detection sensitivity amplifier at the camera. The fixation clip can be removed, and the nuclear radiation detection sensitivity amplifier is adhered to a lens for use. According to the invention, the amplifier has the advantages of simple structure, low cost, easy use, good reproducibility and long-term stability; and the nuclear radiation detection sensitivity amplifier can be used with an ideal radiation pick-up algorithm to effectively improve the nuclear radiation detection efficiency and precision of the camera and reduce hazards caused by a radiation source which is exposed for a long time.

Description

technical field [0001] The invention belongs to the technical field of nuclear radiation detection, and in particular relates to a nuclear radiation detection sensitivity amplifier. Background technique [0002] Since the discovery of radioactive substances, humans have been committed to the application of radiation in various aspects such as industry, agriculture, medicine, resources, environment, and military affairs, such as non-destructive testing, radiation therapy, and radiation treatment, which have played an important role in improving human life. effect. However, due to problems such as lax supervision or related operational errors, the loss of radioactive sources and radiation exposure incidents also occur from time to time, threatening public safety. As far as the radioactive source itself is concerned, due to its high energy, it can cause ionizing radiation, cause cell lesions or destroy cell tissues, thus causing harm to the human body. Therefore, reasonable p...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is the problem of low sensitivity or even inability to detect the radiation of ordinary monitoring cameras. A new device is proposed to improve the sensitivity of the monitoring camera to detect radiation sources, which reduces the detection cost of radiation information, and can realize the detection of radiation at the same time. Quickly locate the radiation source, reducing the physical damage to the source-finding staff during the source-finding process
