The Idaho National Engineering Laboratory Site environmental report for calendar year 1992

Final environmental impact statement for the construction and operation of an independent spent fuel storage installation to store the Three Mile Island Unit 2 spent fuel at the Idaho National Engineering and Environmental Laboratory. Docket Number 72-20

“…Radioactivity still remaining in the environment as a result of atmospheric testing of nuclear weapons also contributes to the background radiation level, although in very small amounts. The natural background dose for residents of the ESRP is estimated at 351 millirem [3.51 mSv] per year, with more than half (about 200 millirem r2.00 nBv] per year) caused by the inhalation of radioactive particles formed by the decay of radon (Hoff et al, 1992, National Council on Radiation Protection and Measurements, 1987).…”

“…These results are discussed separately below for onsite and offsite environments. (Hoff et al, 1992).…”

“…One exception is depredation hunts, which were negotiated between the Idaho Department of Fish and Game and DOE (Hoff et al, 1993) (Hoff et al, 1993).…”

“…(Hoff et al, 1992 from the INEEL site boundary (and much further from most major emissions sources) , these levels can be considered representative of general background.…”

“…K-40 also is found naturally in human bodies worldwide in sufficient concentrations to produce radiation doses of 14 to 27 mrem/yr to various organs (NCRPM 1987). The average concentration of naturally occurring K-40 in INEL surface and near-surface sediments is 19 pCi/g (Hoff et al 1993). These sediments are used for backfill in the SDA.…”
