Radiation Dose Calculator
What is a Radiation Dose?
A radiation dose measures the amount of ionizing radiation energy absorbed by the body or an object. It’s a critical metric in fields like nuclear medicine, radiology, radiological protection, and health physics to ensure safety and minimize exposure risks.
The Radiation Dose Calculator helps estimate absorbed, equivalent, and effective doses based on different radiation types and affected body tissues. It supports units like grays (Gy) and sieverts (Sv).
Types of Radiation Dose
Understanding the three main dose types is essential:
- Absorbed Dose (Gy): Energy absorbed per kilogram of matter.
- Equivalent Dose (Sv): Absorbed dose adjusted by radiation type (radiation weighting factor, WR
- Effective Dose (Sv): Equivalent dose further adjusted for tissue sensitivity (tissue weighting factor, WT
Radiation Dose Limits
According to ICRP guidelines:
Occupational exposure:
- 20 mSv/year (average over 5 years), with no more than 50 mSv in any single year
General public exposure:
- 1 mSv/year
Always aim to minimize exposure following the ALARA principle (As Low As Reasonably Achievable).
