Converting from Gray (Gy) to Millisievert (mSv) | Radiation

What is Gray (Gy)

The Gray (Gy) is the unit of absorbed dose of ionizing radiation in the International System of Units (SI). It measures the amount of energy absorbed per unit mass of an object, with 1 Gray equal to 1 joule per kilogram.

What is Millisievert (mSv)

The Millisievert (mSv) is a unit of equivalent dose, which quantifies the biological effect of radiation on living tissue. It takes into account the type of radiation and its potential harm to human health. One Millisievert is equivalent to 0.001 Sievert.

Conversion Formulas

The default conversion between Gray (Gy) and Millisievert (mSv) is as follows:

• 1Gy=1000mSv

• 1mSv=0.001Gy

Examples

1. Converting 14 Gy to mSv:

14Gy=14×1000=14000mSv

2. Converting 3 mSv to Gy:

3mSv=3×0.001=0.003Gy

3. Converting 8 Gy to mSv:

8Gy=8×1000=8000mSv

Through these examples, you can see how the conversions are done between Gray (Gy) and Millisievert (mSv). These conversions are crucial in the field of radiation protection and dosimetry to assess and manage radiation exposure effectively.
