SOME PROPERTIES OF RADIOACTIVE FALLOUT: SURFACE DETONATION COULOMB C
Abstract
Data on the ionization-rate decay, activity-particle size distributions, and exposure rate-conversion coefficient for soil and filter- collected samples of fallout from Shot Coulomb C have been presented. Radiochemical analyses of selected samples permitted the correlation of the results in terms of equivalent fission levels relative to the Mo-99 content of the samples. The gross fractionation ratio relative to normal U-235 fission products was generally lower than observed for the fallout from larger yield explosions at all times from 240 to 6,000 hours after detonation. Individual radionuclide radiochemical 'R' values were determined for Sr-89, Zr-95, Te-132, and Ba-140. No soil induced activities were detected to be present in significant amount at the time the analyses were carried out at around H + 270.
