| Description/Abstract | Five compact, portable, continuous /sup 222/Rn monitors have been constructed inhouse. Printed data can be obtained from intervals ranging from 10 minutes to 990 minutes. One hour count interval provides a lower limit of detection of 0.03 pCi /sup 222/Rn/l/sup -1/ which is sufficient for measurement of any environmental level encountered. Calibration of the units was accomplished in the EML radon calibration room and the typical calibration factor is 165 counts per hour per pCi /sup 222/Rn/l. The units are now being field tested. Two indoor/outdoor pairs are located in a single family dwelling and in a high rise apartment. One unit is being used for special studies. |
