F1 

Internal exposures associated with subsurface 

maintenance and repurposing activities in 

Building 10 during the residual period should 

be explicitly included in the ER. NIOSH 

should not assume that there is sufficient 

conservatism inherent in the internal dose 

reconstruction methods employed in the ER to 

account for these exposures. 

In October 2017, NIOSH (with SC&A’s 

participation) conducted interviews with 

personnel knowledgeable of site activities 

during the residual period. Upon review of 

that data, NIOSH agrees that the subsurface 

exposure provided in the current ER requires 

improvement to reflect more accurately the 

actual exposure potential during the residual 

period. The model currently in development 

should, with exception of calculations, be 

approved by the end of February 2018.

F2 

NIOSH incorrectly transcribed some of the 

Landauer film badge dosimetry reports and 

incorrectly calculated annual 95th percentile 

external penetrating doses to workers in the 

residual period. 

NIOSH will correct this in the revised ER.
