Contamination was later found on refuse from the Hanford Site in the city landfill. Environmental permits were obtained to move the contaminated waste back onto the Hanford Site, where it was placed in low-level waste burial grounds. An investigation team worked aggressively to determine the source of contamination. In one extreme instance approximately 260 nanocuries of strontium-90 were found on nine captured fruit flies. No rapid notification process existed for informing the waste transportation workers to stop hauling refuse.
Control is particularly important when such fixatives are used in areas open to the environment.
Monitor materials originating from the vicinity of contaminated areas with a graded approach, especially those items destined for offsite disposition.
