ENGINEERING – CONVERION & CONTANT (ENGINEERING) CALCULATOR
Radiation Dose Unit
A precise tool.
What is the Radiation Dose Unit & How does it work?
The gray (Gy) is the SI unit of absorbed dose, representing one joule of energy deposited per kilogram of material. Historically, the rad was used, where 1 Gy = 100 rad.
The sievert (Sv) quantifies the biological effect of ionising radiation, incorporating a quality factor. The rem is the older unit, where 1 Sv = 100 rem.
Both absorbed and equivalent dose units can be interconverted using simple factors.
D_{\mathrm{rad}} = 100\, D_{\mathrm{Gy}} quad , quad D_{\mathrm{rem}} = 100\, D_{\mathrm{Sv}}
D = dose

Frequently Asked Questions
How do I convert Gy to rad?
To convert gray (Gy) to rad, multiply the Gy value by 100. For example, 2 Gy is equal to 200 rad.
What is the difference between Gy and Sv?
The gray (Gy) measures absorbed dose in joules per kilogram, while the sievert (Sv) quantifies the biological effect of radiation by incorporating a quality factor.
How do I convert rem to Sv?
To convert rem to sievert (Sv), multiply the rem value by 0.01. For example, 50 rem is equal to 0.5 Sv.
What is the relationship between Gy and Sv?
The relationship between gray (Gy) and sievert (Sv) depends on the type of radiation and the tissue affected. The Sv is always greater than or equal to the Gy, with a factor called the quality factor (Q).
Can I use this calculator for medical applications?
Yes, this calculator can be used for medical applications where radiation dose conversion is necessary.
How do I convert Sv to rem?
To convert sievert (Sv) to rem, multiply the Sv value by 100. For example, 1 Sv is equal to 100 rem.
What are some common uses for this calculator?
This calculator is commonly used in radiation therapy planning, nuclear medicine, and radiological safety assessments where dose unit conversions are required.
