Convert Rads to Picograys
Convert Rads (rad) to Picograys (pGy) instantly and accurately.
Conversion Formula
pGy = rad × 10000000000
About Rads
The rad (rad) equals exactly 0.01 Gy = 100 erg/g. The pre-SI unit of absorbed dose, defined by the ICRU in 1953, still widely used in the US in radiation therapy (cGy = rad numerically), radiation biology, and NRC regulations. Whole-body 50% lethal dose (LD50) for humans ~350-450 rad. 1 rad = 0.01 Gy = 1 cGy.
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.
