Radiation Detection

We are constantly exposed to all kinds of natural radiation sources in our daily lives. Some of them are natural radionuclides such as ⁴⁰K, ²³⁸U, ²³²Th, etc. coming from cosmic rays, soil, and building materials. It is called external radiation source. While the other part can come from human inhalation of air (mainly from Rn in the air) and ingested food, which is considered as internal radiation source. It is generally acknowledged that the main source of radiation harm to human health is inhalation and followed by external radiation and ingestion. In addition to natural radionuclides, artificial radionuclides such as ¹³⁷Cs, ¹³⁴Cs, ⁹⁰Sr, ¹⁰⁶Ru, ²⁴⁰Pu, etc. from nuclear tests are also present in the soil. The release of radioactive efflux from nuclear facilities is causing district soil pollution. With the rapid development of the atomic energy industry and nuclear tests around the world, radioactive waste water and waste residue have entered the soil through surface runoff result in radioactive contamination of the soil. Soil radioactive pollution refers to the radioactive pollutants entering the soil along with human activities, which causes the radioactive level of the soil exceeding the natural background value or the related standard requirement. The radioactivity content varies with the type of soil. Soil radioactive pollution can pose a serious threat to human survival by destroying body tissue and DNA. The assessment of radioactive elements in the soil is very important.

Radiation is energy in the form of emission waves or particles. A radioactive atom will attempt to reach stability by emitting radiation, such as, alpha rays, beta rays or gamma rays. The basic principle of radioactivity detection is based on various effects generated by the interaction between rays and substances, including ionization effects, luminescence effects, thermal effects, chemical effects, and nuclear reactions that can produce secondary particles, etc.
