About Grays
The gray (Gy) is the SI coherent unit of absorbed radiation dose, defined as 1 joule of energy deposited per kilogram of matter. Named after Harold Gray (British radiobiologist, 1905-1965). Used globally in radiotherapy: curative tumour doses 40-80 Gy fractionated; total body irradiation before bone marrow transplant 12-14 Gy. 1 Gy = 1 J/kg = 100 rad.
About Picograys
The picogray (pGy) equals 10⁻¹² Gy. Microdosimetry simulations of α-particle traversals through single cells report mean specific energies in the pGy range; computed dose kernels for ²¹⁰At and !21³Bi targeted alpha therapy on individual cell clusters are expressed in pGy. 1 pGy = 10⁻¹² Gy = 10⁻³ nGy.
