Air samplers were used to test for plutonium
Generally, these air samplers showed no detectable activity,
but did record as high as 0.24 d/min-meter

of beta-gamma activity.
Urine samples of full-time
workers in the area never showed alpha-particle activities larger than
a very small fraction of tolerance (Kinsey, 1973).

these findings, the precautionary quarantine on Runit was lifted on
