4. Normal radiation levels are the following The worldwide average background dose for a human being is about 2.4 (millisieverts) mSv per year

5. SI multiples and conversions Frequently used SI multiples are the millisievert (1 mSv = 10 −3 Sv = 0.001 Sv) and microsievert (1 μSv = 10 −6 Sv = 0.000001 Sv).SI multiples Equivalent doseEquivalent dose is measured in the United States in rem [3] :United Statesrem [3] 1 rem = 0.01 Sv = 10 mSv 1 mrem = 0.00001 Sv = 0.01 mSv = 10 μSv 1 Sv = 100 rem = 100,000 mrem (or millirem) 1 mSv = 100 mrem = 0.1 rem 1 μSv = 0.1 mrem The rem and millirem (abbreviated mrem), as with other customary units in the United States, are in wider use among the general public, many industries, and government. [3] However, SI units such as the sievert are frequently encountered in academic, scientific, and engineering environments.milliremcustomary units in the United States [3]SI [edit] Dose examplesedit

6. Symptom benchmarks Symptoms of acute radiation (dose received within one day): [20] [20] 0 – 0.25 Sv (0 – 250 mSv): None 0.25 – 1 Sv (250 – 1000 mSv): Some people feel nausea and loss of appetite; bone marrow, lymph nodes, spleen damaged.nausealoss of appetitebone marrow lymph nodesspleen 1 – 3 Sv (1000 – 3000 mSv): Mild to severe nausea, loss of appetite, infection; more severe bone marrow, lymph node, spleen damage; recovery probable, not assured.infection 3 – 6 Sv (3000 – 6000 mSv): Severe nausea, loss of appetite; hemorrhaging, infection, diarrhea, peeling of skin, sterility; death if untreated.hemorrhaging diarrheapeeling of skinsterilitydeath 6 – 10 Sv (6000 – 10000 mSv): Above symptoms plus central nervous system impairment; death expected.central nervous system Above 10 Sv (10000 mSv): Incapacitation and death.Incapacitation

7. Hourly dose examples Average individual background radiation dose: 0.23μSv/h (0.00023mSv/h); 0.17μSv/h for Australians, 0.34μSv/h for Americans [10][5][11] [10][5][11] Highest reported level during Fukushima accident: 1000 mSv/h reported as the level at a pool of water in the turbine room of reactor two.
