Convert Picograys to Megagrays
Convert Picograys (pGy) to Megagrays (MGy) instantly and accurately.
Conversion Formula
MGy = pGy × 1.000000000e-18
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.
About Megagrays
The megagray (MGy) equals 10⁶ Gy. Doses in the MGy range destroy virtually all molecular structures. Radiation chemistry of water reaches radical recombination equilibrium above 1 MGy; neutron-irradiated reactor pressure vessel steels accumulate fast-neutron damage equivalent to 0.01-1 MGy over a 40-year lifetime. 1 MGy = 10⁶ Gy = 10⁸ rad.
