Targeted radiotherapies maximize cytotoxicty to cancer cells. In vivo α-generator targeted radiotherapies can deliver multiple α particles to a receptor site dramatically amplifying the radiation dose delivered to the target. The major challenge with α-generator radiotherapies is that traditional chelating moieties are unable to sequester the radioactive daughters in the bioconjugate which is c...
Abstract Certain nuclear isomers are well known to affect nucleosynthesis with important observable consequences (e.g., 26 Al and 180 Ta). We study the impact of in context rapid neutron capture process ( r -process) nucleosynthesis. demonstrate that dynamically populated some far from thermal equilibrium; this makes them astrophysical isomers, or “astromers.” compute thermally mediated transit...
Based on the last presented reports of UNSCEAR, inhalation of radon gas and its short-lived decay products is a major contributor to the human exposure from natural radioactivity. Lung cancer is the known effect on human health from exposure to radon in air. Radon is found in outdoor air of buildings of all kinds. The main important isotope of radon is 222Rn. Radon (222Rn) is a noble gas...
Many contaminants exhibit decay (radioactive decay, consumed by bacteria, heat loss or evaporation through the surface, dissolution by turbulence). For a non-symmetric river with non-reversing flow, the effects of decay are allowed for in specifying the diffusion centre i.e. the optimal postion for a steady discharge. Three families of exact solutions are presented that illustrate the effect on...
