Quarterly environmental radiological survey summary second quarter 1998 100, 200, 300, and 600 areas
This report provides a summary of the radiological surveys performed in support of near-facility environmental monitoring at the Hanford Site. The Second Quarter 1998 survey results and the status of actions required are summarized. Eleven of the ninety two environmental radiological surveys scheduled during April, May, and June were performed as planned. Sixty seven of the surveys were conducted at Project Hanford Management Contractors (PHMC) sites and twenty five at Environmental Restoration Contractor (ERC) sites. Contamination above background levels was found at twenty one of the PHMC waste sites and two of the ERC waste sites. Contamination levels as high >1,000,000 disintegrations per minute (dpm) per 100 Cmz were reported. Of these contaminated surveys twelve were in Underground Radioactive Material (URM) areas, three were in unposted areas and eight were in contamination areas. The contamination found within six of the UFW and four of the CA areas was immediately cleaned up and no further action was required. The remaining six URM, four CA, and three unposted sites were posted and will require decontamination. Radiological Problem Reports (RPR`s) were issued and the sites were turned over to the Landlord for further action as required. During the second quarter of 1998, 1.2 hectares (3.O acres) were stabilized and radiologically down posted from Contamination Area (CA)/Soil Contamination (SC) to URM. Four Surveillance Compliance Inspection Reports (SCIRS) remained open and had not been resolved. Tank Farms Operations has responsibility for the unresolved SCIRS.
