The gray (Gy), which is the SI unit of absorbed dose, corresponds to the absorption of 1 J of energy per kilogram of tissue. The rad (radiation absorbed dose) corresponds to the absorption of 1 10â2 J of energy per kilogram of tissue. Thus, 1 Gy = 100 rads. The rad is the unit most often used in medicine.
UV-B radiation is uniquely absorbed by the ozone layer. Most of the more energetic solar radiation has been absorbed by other atmospheric constituents before the ozone layer. â¦ The atmosphere stops the classical alpha, beta and gamma radiations. Neutrons decay with time, and are also slowed a bit.
