Radiological survey of the former Shpack Landfill, Norton, Massachusetts

“…apply site-specific measures where needed. Rn-222 emanation to the atmosphere from facility surfaces or openi g shall not (1) exceed an average release rate of 20 pCi/m I s , or (2) increase the annual average Rn-222 concentration at or above any location outside the facility site by more than 0.5 pCi/l.…”

“…Rn-222 concentrations in the atmosphere above facility surfaces or openings shall not (1) exceed 100 pCi/l at any given point, or an average concentration of 30 pCi/l for the facility site, or (2) exceed an average Rn-222 concentration at o r above any location outside the facility site of 3.0 pCi/l (above background).…”

“…The samples were sent to DOE'S Niagara Falls Storage Site (NFSS), where they were analyzed on site for radium-226 and uranium-238 using the high resolution gamma spectrometry system in the FUSRAP Count Trailer No. 1 (Ref. 2).…”

“…Surface water at the site drains into Chartley Brook and Chartley Pond to the east and north, respectively. Within the landfill, the depth to the water table is generally 1.5 m (5 ft) or less; the predominant groundwater flow is north to Chartley Pond (Cottrell et al 1981). About one-half to ttu'eequarters of the Shpack landfill is within a 100-year floodplain (Peterson 1981).…”

“…The geology of the area consists of glacial deposits overlying bedrock. The glacial overburden ranges in thickness from 4.6 to 7.6 m (15 to 25 ft) and is overlain by organic deposits (peat) varying in thickness from 1.5 to 9.1 m (5 to 30 ft) (Cottrell et al 1981). The bedrock is folded, faulted, and metamorphosed sedimentary rock of Permsylvemian age.…”
