About Radiation Unit Conversion

Radiation units measure the amount of energy absorbed by matter and the biological effects of radiation exposure. The gray (Gy) is the SI unit for absorbed dose, representing one joule of energy absorbed per kilogram of matter. The rad is the traditional unit, where 1 rad equals 0.01 Gy.

The sievert (Sv) is the SI unit for equivalent dose, which accounts for the biological effectiveness of different types of radiation. The rem is the traditional unit, where 1 rem equals 0.01 Sv. These units are crucial for radiation protection, medical imaging, and nuclear safety.

Our converter provides accurate conversions between these units, including common prefixes like milli- and micro-. This is essential for comparing radiation measurements across different standards and ensuring proper radiation safety protocols in medical, industrial, and research applications.

⚠️ Important Notes

Radiation Safety: Always follow proper radiation protection protocols and regulations.
Medical Applications: Consult qualified medical professionals for radiation dose interpretation.
Regulatory Compliance: Ensure conversions meet applicable safety standards and regulations.
Precision: Radiation measurements require high precision for safety-critical applications.
