What is radiation sickness?(1)

Radiation sickness， it is also be called  radiation poisoning,   is illness and symptoms resulting from excessive exposure to radiation. Exposure may be accidental or intentional

So far, There are two basic types of radiation: ionizing and nonionizing.

Nonionizing radiation comes in the form of light, radio waves, microwaves and radar. This kind of radiation usually does not cause tissue damage.

Ionizing radiation is radiation that produces immediate chemical effects on human tissue. X-rays, gamma rays, and particle bombardment (neutron beam, electron beam, protons, mesons, and others) give off ionizing radiation. This type of radiation can be used for medical testing and treatment, industrial and manufacturing purposes, weapons and weapons development, and more.

Radiation sickness results when humans (or other animals) are exposed to very large doses of ionizing radiation. Radiation exposure can occur as a single large exposure (acute), or a series of small exposures spread over time (chronic).

Radiation sickness is generally associated with acute exposure and has a characteristic set of symptoms that appear in an orderly fashion. Chronic exposure is usually associated with delayed medical problems such as cancer and premature aging, which may happen over a long period of time.

And we will introduce more knowledge about the degree of this sickness and the cause of it in next article
