For a long time now, microorganisms have been employed as a tool in the interpretation of the biological activities of radiations, usually in terms of lethal and genetic effect. In order to maintain standard conditions, recent investigations have been careful to prevent growth during irradiation. Whereupon, the lethal and genetic effects usually have been affected proportionately over a wide do...

In a recent discussion relating to environmental health, Mark D. Hollis (1) indicated that public health officials will be responslible for protecting the population against the harmful effects of ionizing radiation. Ionizing radiations result from the disintegration of unstable nuclei and are damaging to living tissue. The radiation may originate from an external source or from radioactive mat...

Detection and characterization of potentially harmful radiation sources is one of common problems encountered in the context of homeland security as well as in safeguarding of radioactive isotopes used in industrial or medical practices. Any improper or insecure storage of radioactive material may cause a substantial harm to humans and to the environment. The task of detecting relatively weak, ...

Radioactive components of the interstellar medium provide an entirely-different and new aspect to studies medium. Injected from sources nucleosynthesis, unstable nuclei decay along their trajectories. Measurements can occur through characteristic gamma rays that are emitted with decay, or in cosmic material samples abundances parent daughter isotopes as they change decay. The dynamics flows wit...

This second phase of the study of "Uptake of Radioactive Phosphorus in Experimental Tumors" deals with the uptake of P32 by malignant tissue, in comparison with that by inflammatory ocular tissue, and an investigation of the influence of vascularity upon the uptake of P32 in normal, inflammatory, and neoplastic tissues. There has been some speculation as to the effect of vascularity upon the up...

This paper starts from the premise that radioactive material, generated as a by-product of the British nuclear industry, already exists in significant quantity. The question of what should be done with this material therefore needs to be answered, even if no more of it is created. Whether the industry should continue producing radioactive waste is a legitimate question, and one which raises sig...

After gaining considerable expertise in establishing and exercising waste management strategy by immobilization of high-level radioactive liquid waste (HLW) in borosilicate glass matrix followed by its interim storage, it is envisaged to focus on geologic disposal of radioactive waste packages. The multi barrier disposal system is considered one of the options for isolation of radioactive waste...
