How many rads are equivalent to one gray?

One gray (Gy) is defined as the absorption of one joule of radiation energy per kilogram of matter. To convert grays to rads, it is important to understand the relationship between these two units. The rad (radiation absorbed dose) is a legacy unit that has been largely replaced by the gray in SI units but is still widely used in certain contexts.

1 gray is equal to 100 rads. This means that when an exposure of 1 gray is referenced, it corresponds to an absorbed dose of 100 rads. This conversion factor is crucial for anyone working in radiation therapy and dosimetry, as it helps in calculating appropriate doses for treatment planning and radiation safety.

Understanding this conversion is key in the field of medical dosimetry, where precise measurements of radiation doses are essential for effective treatment while minimizing damage to healthy tissues.
