Internal Radiation Dose (Inhalation)

Manage Bookmarks
Convert the internal exposure dose from inhaled radioactive material to an effective dose (in sieverts).
The radioactive substances are limited to iodine 131, cesium 134, and cesium 137.
1 Becquerel is the intensity of radioactivity emitted per 1 second by 1 nuclear decay.
Sievert is a unit of radiation dose that indicates the degree of impact on the human body.
