Radiation Dose Conversion Calculator

Convert between different radiation dose units and calculate biological effects

About this calculator

The Radiation Dose Conversion Calculator is an essential tool for medical professionals, radiation safety officers, and researchers who need to convert between different radiation dose units such as Gray (Gy), rad, Sievert (Sv), and rem. This calculator also estimates biological effects by applying radiation weighting factors and tissue weighting factors. It's particularly valuable for radiation therapy planning, occupational safety assessments, and nuclear medicine applications where accurate dose calculations are critical for patient safety and regulatory compliance.

How to use

Enter your radiation dose value and select the input unit from the dropdown menu. Choose your desired output unit for conversion. If calculating biological effects, specify the radiation type and tissue involved. The calculator will automatically apply appropriate weighting factors and display the converted dose values along with biological effectiveness estimates.

Frequently asked questions

What's the difference between absorbed dose and equivalent dose?

Absorbed dose (Gray/rad) measures energy deposited per unit mass, while equivalent dose (Sievert/rem) accounts for biological effectiveness of different radiation types.

When should I use radiation weighting factors?

Use radiation weighting factors when converting from absorbed dose to equivalent dose to account for the biological effectiveness of different radiation types.

What are common radiation dose limits for workers?

Annual dose limits are typically 20 mSv (2 rem) for radiation workers and 1 mSv (0.1 rem) for the general public.
