Much of that exposure comes from the sun, from cosmic radiation from space, one would have to receive a one-time dose of at least 1 to 2 Sieverts. Sievert (Sv), unit of radiation absorption in the International System of Units (SI).

A banana equivalent dose can also be expressed in sieverts, it is equal to 0.1 microsieverts. Bananas are used because they contain potassium-40, a radioactive isotope that naturally occurs in some foods. Definition CIPM definition of the sievert. The SI definition given by the International Committee for Weights and Measures (CIPM) says: "The quantity dose equivalent H is the product of the absorbed dose D of ionizing radiation and the dimensionless factor Q (quality factor) defined as a function of linear energy transfer by the ICRU" Convert equivalent dose units.

A microsievert (μSv) is a decimal fraction of the SI derived unit of equivalent radiation dose, effective dose, and committed dose. One sievert is the amount of radiation necessary to produce the same effect on living tissue as one gray of high-penetration x-rays.
