Beta and Gamma Dose Rates From Terrestrially Distributed Sources

Description: Report that examines the dose rate of radiation in the air and in a test subject due to radioactive materials (uranium, thorium, and potassium) that are present in the ground. The test subject in these experiments is a water cylinder that is meant to receive radiation in a manner similar to a person.

Abnormal grain growth in M-252 and S-816 alloys

Description: Report discussing an experimental investigation was carried out on air- and vacuum-melted M-252 and S-816 alloys to find conditions of heating and hot-working which resulted in abnormal grain growth. The experiments were mainly limited to normal conditions of heating for hot-working and heat treatment and normal temperatures of solution treatment were used to allow grain growth after susceptibility to abnormal grain growth was developed by various experimental conditions. Results indicated that small reductions of essentially strain-free metal were the basic cause of such grain growth.
