Use this simple atomic physics calculator to calculate equivalent dose absorbed by tissue for radiological protection online.

Radiation weighting factors WR (formerly termed Q factor) according to ICRP report 103

Equivalent Dose - Radiological Protection Calculation

Formula:

HT = D × Q

where,
HT - is the equivalent dose absorbed by tissue T
D - is the absorbed dose in tissue T by radiation type R
WR or D - is the radiation weighting factor defined by ICRP regulation
