radiation detectors

Since the discovery of X-rays by the German scientist Roentgen in 1895, the applied research of nuclear technology has been deepening. Gradually, radiological diagnosis and radiotherapy came into being. From the early x-ray and CT machines to the present linear gas pedal, ECT, PET-CT, radionuclide therapeutic drugs, proton and heavy particle gas pedals, these technologies have brought great progress to human medicine.digital nitrate tester However, we must also recognize that nuclear technology itself is like a double-edged sword. Once nuclear radiation energy is deposited in the human body and reaches a certain level, it will cause ionization and excitation of biologically active molecules in the body. As a result, the molecular structure of nucleic acids, proteins and enzymes in the body will change and biological activity will be lost, thus causing a series of radiation damage.

When applying nuclear technology to analyze radioactive diagnosis and treatment, it is necessary to control the radiation dose of the system through strict management, set dose limits, and at the same time do a good job of radiation protection and monitoring.radiation detectors Only a reasonable, standardized application of nuclear radiation technology, in order to get a better service for the development of public mental health.

Radiation protection:

The basic task of radiation protection is to prevent and control radiation hazards, to protect the health and safety of those engaged in radiological work, the public and their descendants, and to protect the environment in order to promote the sustainable development of nuclear-related endeavors,geiger counter handheld including the application of nuclear medicine at the industrial level. Radiation protection can be categorized into workplace protective shielding, personal protection of staff and radioactive waste disposal.

Protective Shielding:

Suitable shielding materials such as lead, lead glass, plexiglass, etc. are used according to the types of radiation commonly found in hospitals. For the protection and decoration of diagnostic radiography equipment rooms and supporting infrastructure, personalized protection design can also make the examination environment more friendly, in line with the development trend of humanization of the medical environment.

The places to be shielded in hospitals include: radiological diagnostic equipment rooms, public areas for nuclear medicine patients, radionuclide high activity areas, radionuclide drug treatment areas, radionuclide drug storage areas and radioactive waste storage areas.

Radiation Monitoring.

The basic principle of radiation monitoring is to utilize the nuclear physical effects, chemical effects, or phenomena resulting from the interaction of nuclear radiation with matter, and to use appropriate radiation detectors to record nuclear radiation, thereby enabling the identification of the type of nuclear radiation and the measurement of the intensity, energy or energy spectrum, and half-life of nuclear radiation. According to the medium interacting with nuclear radiation and the properties of the detected radiation, different radiation needs to be detected with different detectors. Commonly used radiation detectors include gas detectors, scintillation and luminescence detectors, semiconductor detectors, nuclear trail detectors, neutron detectors, and energetic particle detectors.

The main research purpose of radiation monitoring is to quantitatively or qualitatively determine the dose received by the managers of their own vocational education work and the public social group, including checking the effectiveness of radiation shields and protective technological equipment, proposing timely statutes and measures of protection, detecting problematic abilities in radiological operations, as well as potential traffic accidents, preventing that the people involved in the accounting vocational training work are not exposed to higher doses of irradiation or to the surrounding residents of the harmful factors affecting the handling of personal dose monitoring, site monitoring and monitoring of radioactive contamination of the environment.

In terms of environmental monitoring and protection, it is necessary to carry out real-time monitoring of radioactive data in key areas of the hospital, such as computer rooms for general radiological equipment, in order to provide early warning in the event of abnormalities. In addition, in order to protect medical personnel, it is necessary to have real-time radiation protection equipment and dose-detection equipment in order to have real-time knowledge of the cumulative dose of medical personnel.
