Background radiation level is widely used in radiological health fields as a standard for setting exposure limits. [1] Presumably, a dose of radiation which is equivalent to what a person would receive in a few days of ordinary life will not increase their rate of disease measurably.

The embryo and fetus are considered highly sensitive to radiation exposure. [8] Complications from radiation exposure include malformation of internal organs, reduction of IQ, and cancer formation. [8] The SI unit of exposure is the coulomb per kilogram (C/kg), which has largely replaced the roentgen (R). [9]
English: Radiation Dose Chart by Randall Munroe as part of the webcomic xkcd (SVG version of ). In response to concerns about the radioactivity released by the Fukushima Daiichi nuclear disaster:Fukushima Daiichi nuclear disaster in 2011, and to remedy what he described as "confusing" reporting on radiation levels in the media, Munroe created a chart of comparative radiation exposure levels.
A dose rate is quantity of radiation absorbed or delivered per unit time. It is often indicated in micrograys per hour (μGy/h) [1] or as an equivalent dose rate Ḣ T in rems per hour (rem/hr) or sieverts per hour (Sv/h).
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.
A banana contains naturally occurring radioactive material in the form of potassium-40.. Banana equivalent dose (BED) is an informal unit of measurement of ionizing radiation exposure, intended as a general educational example to compare a dose of radioactivity to the dose one is exposed to by eating one average-sized banana.
In the 1930s the roentgen was the most commonly used unit of radiation exposure. This unit is obsolete and no longer clearly defined. This unit is obsolete and no longer clearly defined. One roentgen deposits 0.877 rad in dry air, 0.96 rad in soft tissue, [ 9 ] or anywhere from 1 to more than 4 rad in bone depending on the beam energy. [ 10 ]
