Radioactivity in the environment occur due to natural, terrestrial, extra-terrestrial factors or caused by human activity. Food stuffs that grown soil which containing radioactive elements may get deposited absorbed foods. Wild growing mushrooms can accumulate many types of toxicological, nutritional and elements. So, are considered as good bio-indicators determine environmental pollution radia...

Abstract The IUPAC–IUGS joint Task Group “Isotopes in Geosciences” (TGIG) has evaluated the published literature on half-lives of six long-lived, geologically relevant radioactive nuclides. Where conflicting estimates are present, it is necessary to first identify any systematic bias accordance with metrological traceability and exclude biased from further consideration. TGIG recommends three r...

The bulk of bricks made worldwide are burnt clay bricks, and this volume manufacture requires 230 - 242 million m3 agricultural land. This corresponds to 25,500 hectares rich farmland at a depth 1 meter. type exploitation will have substantial detrimental impact on national food security. According the present need, efficient use industrial waste, such as fly ash, is necessary. So it becomes ve...

Abstract The dynamics of high-energy proton-induced spallation reactions on target nuclides 56 Fe, 58 Ni, 107 Ag, 112 Cd, 184 W, 181 Ta, 197 Au, and 208 Pb are investigated with the quantum molecular transport model motivated by China initiative Accelerator Driven System (CiADS) in Huizhou Spallation Neutron Source (CSNS) Dongguan. production mechanism light fission fragments is thoroughly anal...

In order to ensure the long-term effective isolation of radionuclides from human beings environment, pyrite and magnetite, which exist widely stably in geological can be considered reduce strong mobility high-valence redox-sensitive nuclides low-valence with low mobility. this work, reducing reaction between pyrite, (U, Se, Tc, Np) Gansu proposed-treatment plant area was under simulation by PHR...

Decay heat (DH) is the produced through a radioactive decay of fission products during or after reactor operation. It known as second largest source power in core fission. Being such strong contributor to power, it should be accurately determined at any time Currently, there are two main approaches for DH estimation used simulation codes. One approach based on careful inventorying all target nu...

In order to therapeutically destroy neoplasms, chemotherapy or radiotherapy is usually applied, and in isotope medicine short-lived radionuclides are injected into the tumor ( 59 Fe, 90 Y, 95 Zr, 99 mTc, 106 Ru, 114* In, 147 Eu, 148 155 170 Tm, 177 mLu, 188 Re, 210 Po, 222 Rn, 230 U, 237 Pu, 240 Cm, 241 253 Es). Binary (or neutron capture) therapy a technology designed selectively treat maligna...

As a part of the China-Japan cooperative research on natural radiation epidemiology, we have carried out a dose-assessment study to evaluate the external exposure to natural radiation in the high background radiation areas (HBRA) of Yangjiang in Guangdong province and in the control areas (CA) of Enping prefecture since 1991. Because of the difficulties in measuring the individual doses of all ...
