Radiation Dose Rate Converter
Radiation dose rate is how fast absorbed dose accumulates. The SI unit is the gray per second, but survey meters read in microsieverts per hour and industrial irradiators in kilograys per hour. Absorbed dose (gray) and equivalent dose (sievert) share the same numeric scale here.

About radiation dose rate conversion
Radiation Dose Rate conversion is commonly needed when radiation surveys, sterilisation plants, and occupational monitoring. Natural background is roughly 0.1–0.3 microsieverts per hour, which is a handy reference when reading a survey meter.
