Nuclear medicine is an emerging discipline that uses nuclear technology to diagnose, treat and study diseases. It is the product of the combination of modern science and medicine such as nuclear technology, electronic technology, computer technology, chemistry, physics and biology. Nuclear medicine can be divided into two categories, namely clinical nuclear medicine and basic nuclear medicine or experimental nuclear medicine.
Nuclear medicine is also called atomic medicine. Refers to the medical application of radioisotopes, ray beams produced by accelerators and nuclear radiation produced by radioisotopes. In medical treatment, radioisotopes and nuclear radiation can be used for diagnosis, treatment, and medical science research; in pharmacy, they can be used for research on the principle of drug action, determination of drug activity, drug analysis, and radiation disinfection of drugs.

The composition and principle of lead glass
Lead shot glass is used in the manufacture of optical glass, electric vacuum glass, low temperature sealing glass, radiation protection glass, lead crystal glass, flint optical glass, low melting glass, delay line glass, high refraction bead glass and artware glass, etc. .
Methods of radiation protection
Time protection-shorten the exposure time: shortening the exposure time is a simple and effective protection measure. For this reason, all unnecessary stays in the radiation field should be avoided. Even if the work requires, the stay time in the radiation field should be shortened as much as possible.
How are radioactive sources classified?
Radioactive sources refer to radioactive materials that are permanently sealed in the cladding or tightly consolidated in the covering layer and in solid state, except for materials in the nuclear fuel cycle of research reactors and power reactors.
