Upon investigation it was determined to be a valid alarm. The area was surveyed and revealed two small areas of Strontium-82 contamination, apparently transferred from shoe cover booties. The total contamination was 640 microCuries, all within the Future Production Area (10,450 sq. ft. area). Decontamination of the area was initiated and completed at 1630 EST on January 22, 2021. The three decontamination workers each received 0.4 mREM dose during the clean-up process. No contamination escaped the Future Production Area room. Source/cause of the contamination is being investigated.
