Convert Picograys to Milligrays
Convert Picograys (pGy) to Milligrays (mGy) instantly and accurately.
Conversion Formula
mGy = pGy × 1.000000000e-9
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 Milligrays
The milligray (mGy) equals 10⁻³ Gy and is the standard unit for diagnostic radiology patient doses. CT head scan ~20-60 mGy; abdominal CT ~10-30 mGy; mammography mean glandular dose ~1-3 mGy. IAEA and EU medical exposure directives set diagnostic reference levels in mGy. 1 mGy = 10⁻³ Gy = 0.1 rad.
