DOSE ATTENUATION FACTORS FOR CONCRETE SLAB SHIELDS COVERED WITH FALLOUT AS A FUNCTION OF TIME AFTER FISSION

Abstract

A study was made to investigate the dose attenuation of fallout gamma radiation by vari us thicknesses of concrete roofs of buried fallout shelters as a function of time after a nuclear detonation. A spectrum of energies is used for the fallout source rather than a single average energy as has been done in previous studies. Dose attenuation factors are derived and presented as a function of the above parameters. The Office of Civil and Defense Mobilization recommends a two-week shelter-stay time in the event of a nuclear attack; therefore, also presented is an average dose attenuation factor for any fourteen-day stay time as a function of time of arrival of the fallout or of shelter-entry ti e for various roof thicknesses.
