The following is a summary of information received via email:
On 3/27/20, the Vermont Department of Health (VDH) was notified that a waste transport truck was rejected at a waste facility in Concord, NH. The truck was rejected because radioactive material was detected in the waste. The truck was redirected to Goodenough Rubbish Removal in Brattleboro, VT, and instructed to isolate the waste.
On 3/30/20, VDH Radiation Control responded to the waste center. The radioactive waste was identified as clay cat litter containing I-131 with a maximum dose rate of 8.04 mrem/hr on contact and 0.54 mrem/hr at one meter while background measurements were 10 microR/hr. The waste hauler was instructed to isolate the container in a remote section of the recycling center with the contents covered for 80 days.
On 4/3/20, VDH issued Vermont Information Notice IN 20-001 (Release of humans and animals receiving I-131 therapy) to all Vermont radioactive materials licensees who are authorized to use I-131. This Information Notice recommends all affected licensees review their I-131 administration procedures, patient release criteria, and pet owner release instructions.
On 6/26/20, a VDH inspector returned to survey the material, and found that the radiation levels of the material were indistinguishable from background.
With the decay of the I-131 waste this incident has been closed out by VDH on 8/5/20.
