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.

What is the difference between a radiation source and a radioactive source?

Radiation source refers to a device or substance that can emit or emit ionizing radiation. Some devices may also be sources of radiation that are not necessarily "radioactive".

hat are the characteristics of radiation?

Radioactive decay is spontaneous: the decay of radioisotopes (also called radionuclides) is spontaneous, and it cannot be changed by physical or chemical means.

All kinds of radioactive sources

Medical sources In medicine, radiation sources are used for diagnostic and therapeutic purposes. Radiological clinical diagnostic examination can be divided into two parts
