Xenon and iodine concentrations in the environs of the T and B Plant

Description: A report of seven stack emissions of I-131 at the T and B plants, detailing the relationship between cooling times and dilution factors for the safe emission of the isotope. From the stack sampling, personal exposure limits for an eight and nine hour day are calculated. The effect of atmospheric conditions appears to be negligible, although periods of atmospheric stagnation may have an effect on the I-131 concentration. Environmental effects are minimized by increasing the cooling times of the isotope charge. Downdrafts near the stack emissions during low dilution increase the radiation level, but do not pose any inhalation hazard.

The trend of contamination in the air, the Columbia River, rain, sanitary water, vegetation, and wastes, at the Hanford Works for the period July, August, September 1947

Description: This report summarizes the contamination observed at the Hanford Works and vicinity for the period July, August, and September, 1947. Daily or weekly trends for all sampling locations as included in previous reports are omitted except in those cases where a true trend can be established. Statistical analysis to determine significant values and differences is used whenever possible. The report is divided into the following topic sections: meteorological -- wind conditions; extent of beta contamination in air and radiation level in air; extent of contamination in the Columbia River; extent of beta contamination in rain; extent of alpha and beta contamination in sanitary water; extent of beta contamination on vegetation; and the extent of contamination in Hanford Wastes. An appraisal and review of all the results is considered in detail for each section.

Radioactive contamination in the environs of the Hanford Works for the period January, February, March 1949

Description: This report summarizes in somewhat more detail than the monthly H.I. Environs reports the extent and magnitude of the radioactive contamination detected in the environs of the Hanford Works. Radioactive contamination resulting from the operation of the Hanford Works as well as that found occurring in natural quantities is included. This belated report is being issued merely for the records to serve as a composite summary of measurements already reported in the monthly H.I. Environs reports and covers the quarterly period January, February, and March, 1949.
