High ionizing radiation
WebRadiation may be thought of as energy in motion either at speeds equal to the speed of light in free space—approximately 3 × 10 10 centimetres (186,000 miles) per second—or at speeds less than that of light but … Web23 de jan. de 2024 · At present, the opinions about the interaction between ionizing radiation and the immune system are largely controversial. For long, high-dose ionizing radiation was considered as net immune suppressing mainly due to the exquisite radiosensitivity of the lymphoid system.

WebNuclear reactors are, in general, powerful sources of an entire spectrum of types of ionizing radiation. Shielding used for this purpose is called biological shielding. But this is not the only purpose of radiation shielding. Shields are also used in some reactors to reduce the intensity of gamma rays or neutrons incident on the reactor vessel.
