The record-types include exposure records only; there were no reportable intake records in 2022.
Beginning July 5, 2022, TMl-2 Solutions, LLC began administering their own dosimetry program. TMl-2 exposure after that date will be reported by TMl-2 Solutions, LLC.
During 2022, 469 individuals were monitored with 168 assigned measurable exposures. An apportionment has been performed to segregate TMI, Unit 1 (TMl-1) exposures from TMI, Unit 2 (TMl-2) exposures. Accordingly, 2022 TMl-1 exposure is reported as 20.664 person-rem with 0.069 person-rem assigned to TMl-2, totaling 20.733 person-rem.
Specifics of the 2022 data submitted via the REIRS Web site are as follows:
