Gray (đơn vị)

Gray, ký hiệu: Gy, theo Hệ đo lường quốc tế gray là đơn vị đo lượng hấp thụ bức xạ ion hóa tuyệt đối. Tên đơn vị được đặt theo tên nhà vật lý người Anh Louis Harold Gray.

Định nghĩa

Một gray là lượng hấp thụ bức xạ ion hóa có năng lượng 1 jun của vật hấp thụ có khối lượng 1 kilôgam.

$1 \ \mathrm{Gy} = 1\ \frac{\mathrm{J}}{\mathrm{kg}} = 1\ \mathrm{m}^2\cdot\mathrm{s}^{-2}$
