Dose area product – Quantity used to assess X radiation risk (Gy·cm 2) International System of Units – Modern form of the metric system (SI base units) Orders of magnitude (radiation) – Comparison of a wide range of radiation dosages; Order of magnitude (unit) – Scale of numbers with a fixed ratio
Recognized effects of higher acute radiation doses are described in more detail in the article on radiation poisoning.Although the International System of Units (SI) defines the sievert (Sv) as the unit of radiation dose equivalent, chronic radiation levels and standards are still often given in units of millirems (mrem), where 1 mrem equals 1/1,000 of a rem and 1 rem equals 0.01 Sv.
