What is Radiation Dose?
Radiation dose quantifies the amount of ionizing radiation absorbed by matter. Different types of doses are used depending on the context: absorbed dose measures energy deposited, equivalent dose accounts for radiation type, and effective dose considers organ sensitivity.
Absorbed Dose
Energy deposited per unit mass. Measured in Gray (Gy) or rad. Physical quantity independent of radiation type.
Units:
1 Gy = 100 rad = 1 J/kg
Equivalent Dose
Absorbed dose weighted by radiation quality factor. Accounts for biological effectiveness of different radiation types.
Units:
1 Sv = 100 rem = Gy × Q
Effective Dose
Sum of equivalent doses weighted by tissue sensitivity. Represents total body risk from partial body exposure.
Formula:
E = Σ(H × wT) in Sv
How Does the Radiation Dose Calculator Work?
This calculator converts between different radiation dose units and calculates equivalent and effective doses using quality factors and tissue weighting factors from ICRP recommendations.
