Radiation (Absorbed Dose Rate) Converter

About This Tool

This converter is a specialized tool for health physics, medical physics, and radiation safety, dealing with units of absorbed dose rate. This measures the rate at which energy is absorbed by a material from ionizing radiation. The base unit is the gray per second (Gy/s).

Absorbed dose is a fundamental quantity in dosimetry, as it is the basis for quantifying the biological effect of radiation on tissue. This tool helps professionals convert between the modern SI units and older, historical units.

Tips & Features

• Gray per Second (Gy/s): The gray per second is the SI unit for absorbed dose rate. One gray represents the absorption of one joule of radiation energy per kilogram of matter. The rate is this dose absorbed over time.
• Rad: The rad (radiation absorbed dose) is the older, CGS unit for absorbed dose. One gray is equal to 100 rads. While largely replaced, it is still found in older documentation.
• Dose vs. Equivalent Dose: This tool converts absorbed dose (measured in grays), which is a physical quantity. This is different from the 'equivalent dose' (measured in sieverts), which is a biological quantity that accounts for the different levels of harm caused by different types of radiation.
