What Does a Radiation Protection Technician Do?

Radiation protection technology is a technology that protects radiation workers, the public, and the environment from radiation hazards and pollution. ^[1] The three elements of radiation protection are time protection, distance protection and shielding protection. Radiation protection technology mainly includes radiation detection equipment, radiation protection equipment, radiation shielding materials and other aspects. The entry introduces the characteristics and hazards of radiation; details the principles and elements of radiation protection, and introduces existing radiation detection instruments and protective equipment from the perspective of radiation shielding.

The three main principles of radiation protection include: legitimacy of radiation practice, optimization of radiation protection, personal dose equivalent limit (dose control) ^[3]

The three elements of radiation protection are distance, time and shielding, or the main methods of radiation protection are time protection, distance protection and shielding protection ^[4]

The harm to the human body from radiation is mainly bone marrow suppression, hematopoietic tissue dysfunction, peripheral white blood cell decline, and decreased immune function. Although some compounds have been found to be effective in preventing damage, they are mostly sulfur-containing substances, which are more toxic, so they are less likely to be directly applied to the clinic. Therefore, people expect to develop products with low toxicity that can be used for clinical prevention and treatment. Therefore, the development of anti-radiation products through the research of Chinese herbal medicines with blood circulation, blood supplementation, white blood cell increase and immune function enhancement is the main development direction at present.

Studies have confirmed that Ligustrum lucidum, Houttuynia cordata, Rhodiola, Poria, Chenpi, Hawthorn, Medlar, Yuzhu, Licorice, Coix seed, Astragalus, Zhimu, Quercetin, Ganoderma, Codonopsis, Cistanche, Chuanxiong, Atractylodes , Flat storage, etc., have obvious anti-radiation effects. At present, the common Chinese herbal medicine anti-radiation health foods on the market are developed with these traditional Chinese medicines as the main ingredients.
