Additional Conversion Results
| Unit | Value | Type |
|---|---|---|
| Millisievert (mSv) | 1000.00 | Equivalent |
| Microsievert (μSv) | 1000000.00 | Equivalent |
| Milligray (mGy) | 1000.00 | Absorbed |
| Rad (rad) | 100.00 | Traditional |
Quick Reference
- 1 Gy = 1 Sv (for X-rays, gamma rays)
- 1 rem = 0.01 Sv = 10 mSv
- 1 Sv = 100 rem = 1000 mSv
- Annual limit for radiation workers: 50 mSv
Radiation Units Information
Gray (Gy)
The Gray is the SI unit of absorbed radiation dose. 1 Gy = 1 joule of energy absorbed per kilogram of matter.
Sievert (Sv)
The Sievert is the SI unit of equivalent and effective radiation dose, accounting for biological effects.
Rem (rem)
The Rem is a traditional unit of equivalent dose. 1 rem = 0.01 Sv. Still used in some countries like the USA.

Understanding Radiation Units: A Comprehensive Guide
Radiation unit conversion is essential for professionals in medicine, nuclear industries, and environmental science. This guide explains how to use our radiation unit converter effectively.
Why Radiation Unit Conversion Matters
Different countries and scientific fields use various radiation units. The International System of Units (SI) uses Gray (Gy) for absorbed dose and Sievert (Sv) for equivalent dose, while some regions still use the traditional rem unit. Accurate conversion between these units is critical for safety assessments, regulatory compliance, and scientific research.

Key Conversion Formulas
- 1 Gray (Gy) = 1 Sievert (Sv) for X-rays, gamma rays, and beta particles
- 1 Sievert (Sv) = 100 rem (traditional unit)
- 1 rem = 0.01 Sv = 10 millisievert (mSv)
- 1 milligray (mGy) = 0.001 Gy
- 1 millisievert (mSv) = 0.001 Sv
Practical Applications
Medical professionals use radiation unit conversion to compare diagnostic doses (typically in mSv) with therapeutic doses (often in Gy). Environmental scientists convert between units when measuring background radiation (usually in μSv/h). Nuclear industry workers need to understand both SI units (Gy, Sv) and traditional units (rem) for safety compliance.
Pro Tip
Use the "Radiation Type" selector to get context-specific information. For example, selecting "Medical" will highlight dose comparisons relevant to medical procedures.
