Milligray to Rad (Milligray to Rad)
Result
0.1 Rad
Formula
Rad = Milligray × 0.1
1 Milligray = 0.1 Rad, and 1 Rad = 10 Milligray.
One gray is one joule of energy absorbed per kilogram; the older rad is 0.01 Gy. One becquerel is one decay per second; the curie is exactly 3.7 × 10¹⁰ Bq.
Worked examples
- 1 Milligray × 0.1 = 0.1 Rad
- 10 Milligray × 0.1 = 1 Rad
- 100 Milligray × 0.1 = 10 Rad
Common mistakes
- Gray measures absorbed energy; the sievert measures biological effect (equivalent dose). They are only numerically equal for X-rays, gamma and beta radiation.
- Becquerels describe how radioactive a source is, not the dose a person receives.
