Absorbed & Effective Dose Tool
Calculate absorbed and effective radiation doses for workplace radiation safety assessment.What is Radiation Dose?
Radiation Dose is a measure of the amount of radiation energy absorbed by a material or tissue. It's crucial for assessing radiation safety and ensuring compliance with regulatory limits in workplaces where radiation sources are present.
The calculator provides both absorbed dose (energy absorbed per unit mass) and effective dose (weighted dose considering radiation type and tissue sensitivity) to give a comprehensive assessment of radiation exposure.
Radiation Dose Formulas
Absorbed Dose (Gy)
Energy absorbed per unit mass of tissue
Effective Dose (Sv)
Absorbed Dose × Radiation Weighting Factor × Tissue Weighting Factor
Dose Rate (Gy/h)
Absorbed Dose ÷ Exposure Time
