Radiation Quantities and Units 1 ,[object Object],[object Object]

Radiation Quantities and Units 2 ,[object Object],The radiation weighting factor is necessary because certain radiations are more risky than others.  and X (ext/int) 1,  (internal) 20. The tissue weighting factor is necessary because different tissues have different radiosensitivity . The effective dose is often referred to simply as the dose . Units of H are Sievert Sv (usually mSv used).
