refer to the clarification notes here.

For clarification, the test procedure is as follows:

1. Prior to the over range test, expose the PRD to the same 50 uR/h Cs-137 test field used for the gamma alarm test. Collect 10 readings and calculate the mean response. This is the pre-test response. Remove the source.

2. Expose the PRD at the required over range dose rate using Cs-137 (2x manufacturer’s stated max) for a period of 1 min and verify the PRD indicates that an over range condition exits

3. Remove the over range exposure rate and verify the PRD returns to the response observed prior to the over range exposure within 1 min.

Reference/Explanation

4. Repeat the pre-test exposure with the Cs-137 source placed in the same position used to obtain the pre-test mean. Collect 10 readings and verify that the mean response is within 10% of the mean response obtained prior to the PRD being exposed to the 2x radiation field.
