Dictionary Medical cobalt-60 [′kō‚bȯlt ′siks·tē] (nuclear physics) A radioisotope of cobalt, symbol60Co, having a mass number of 60; emits gamma rays and has many medical and industrial uses; the most commonly used isotope for encapsulated radiation sources. ...
an unstable, radioisotope of cobalt, which emits gamma and beta rays as it decays and has many medical and industrial uses (half-life 5.3 years). Also used to irradiate diamonds to enhance their color, enhancement due to their absorption. Only the surface of the color is instable and they ...
Brachytherapy (BT) uses encapsulated radioactive sources to deliver a high dose to tissues near the source (Correa et al., 2022; Yue, 2006; IAEA-TECDOC-1274, 2002). Source calibration is a crucial part of a comprehensive quality assurance (QA) program for brachytherapy dosimetry. It is ...
This isotope is also intentionally produced, usually in reactors but also to some degree in accelerators for industrial and medical uses, such as for radiation sources for cancer treatment and nondestructive testing of metals and welds. (sup 60)Co may enter the environment as a result of the ...
It uses sealed gamma-ray sources (selenium 75) with high specific activity (800-1200 Ci/g). VNIITFA has developed a mobile gamma-ray system called the RID-K/100 with a cobalt 60 source of activity up to 100 Ci for monitoring... N.,R.,Kuzelev,... 被引量: 3发表: 2004年 Using ...
