How do you measure radiation exposure
WebA measure of the risk of biological harm is the dose of radiation that the tissues receive. The unit of absorbed radiation dose is the sievert (Sv). Since one sievert is a large quantity, radiation doses normally encountered are expressed in millisievert (mSv) or microsievert (µSv) which are one-thousandth or one millionth of a sievert. WebThese could lead to radiation sickness, cancer, genetic mutations, or even death. However, the levels of natural radiation on Earth are generally low and pose little risk to humans. Dosimeters are useful to medical personnel treating a person exposed to acute radiation as they can measure the amount of radiation a person has been exposed to ...
