Effective Dose Rate

 

Effective Dose Rate

The effective dose rate is the rate at which an effective dose is received. It is a measure of radiation dose intensity (or strength). The effective dose rate is therefore defined as:

effective dose rate - definition

In conventional units, it is measured in mSv/sec, Sv/hr, mrem/sec or rem/hr. Since the amount of radiation exposure depends directly (linearly) on the time people spend near the source of radiation, the effective dose is equal to the strength of the radiation field (dose rate) multiplied by the length of time spent in that field. The example above indicates a person could expect to receive a dose of 25 millirems by staying in a 50 millirems/hour field for thirty minutes.
