The inhalation hazard of radioactive fallout
WebAbsorbed beta-radiation dose expected from fallout particles deposited on the skin was estimated by use of the Beta Transmission, Degradation and Dissipation (TDD) model and a Condensed-State Diffusion-Controlled model that describes the mechanism of fission-product absorption in fallout. WebRadionuclides can enter the body by ingestion, inhalation, or injection. Once taken into the body, their radiation effects depend on their anatomic distribution, duration of retention in the body, and rate of radioactive decay, as well as on the energies of their emitted radiations. An internally deposited radioactive element may concentrate in, and thus …

WebIn the dangerous fallout zone up to 10–20 miles from the site of a nuclear detonation, radiation levels may be immediately dangerous to life and health. In areas with such high … WebNTS fallout, whereas the doses from external irradiation are similar for NTS and global fallout. Additionally, as illustrated in Table 1, the mixture of radionuclides contained in fallout is different for the two sources of fallout. As a result, the temporal and geographic distributions of doses from NTS and global fallout differ substantially.
WebApr 11, 2024 · Depleted uranium is used for tank armor, armor-piercing bullets, and as weights to help balance aircrafts. Depleted uranium is both a toxic chemical and radiation health hazard when inside the body. Depleted uranium (DU) is the material left after most of the highly radioactive form of uranium (U-235) is removed from the natural uranium ore. Webdetonation contains fine particles of radioactive dust and other debris that can blanket large areas (tens to hundreds of square miles) with “fallout.” By contrast, most of the radioactive particles dispersed by a dirty bomb would likely fall to the ground within a few city blocks or miles of the explosion.

WebAn evaluation of the acute inhalation hazard from radioactive fall-out materials has been made by analysis of results from animal exposures during field operations and from controlled inhalation studies in the laboratory. WebThe inhalation hazard of fallout particles from a nuclear ground burst has been evaluated with the ICRP Task Group Lung Model and the DELFIC fallout model for the 0.5-kt to 10-Mt yield range. It was found that for the conditions considered in this work, the inhalation of fallout particles does not present a significant radiological hazard.
