To assess the feasibility of using estrogen receptor-directed therapy with Auger electron-emitting ligands for therapy of estrogen receptor (ER)-containing cancers, we synthesized and evaluated the radiotoxicity of several 123I-labeled estrogens to specifically kill ER+ cells in culture. Auger electrons have been previously shown to be of short range, generally less than the dimensions of a cel...

The loading of MOX (Mixed Oxide) fuel in BWRs (Boiling Water Reactors) is considered in this paper in a “once-through” strategy. The fuel assemblies are of the General Electric 8×8 type, whereas the reactor is of the General Electric BWR/6 type. Comparisons with traditional UOX (Uranium Oxide) fuel assemblies revealed that the loading of MOX fuel in BWRs is possible, but this type of fuel creat...

Introduction: Various iodine isotopes are undergoing radioactive decay except Iodine-127 (I-127. Iodine I-131 is unsealed radioactive material used in nuclear medicine for both diagnostic and therapeutic procedures in Royal Hospital since 2006. In radiotoxic classification, I-131 is in group 2 element. I-131 is highly reactive element due to its volatilization nature. Currently...

The transmutation of transuranic (TRU) elements produced by pressurized water reactors (PWRs) can effectively reduce their radioactive hazards. molten chloride salt fast reactor (MCSFR) is a type liquid-fueled (MSR) using fuel in the form salts. MCSFR utilizing neutron spectrum and high actinide fraction considered to be potential for TRU transmutation. An online refueling reprocessing scenario...

As there is no scientific reason to discriminate between chemicals and radioactive substances in terms of environmental risk assessment methodology (ERA), it is now generally recognised (Garnier-Laplace et al., 2006) that the classical ERA method (EC, 2003) may be applied to both of these substances. This is of particular interest in the case of uranium that presents a double ecotoxicity, chemi...

A researcher in society... Since the start of my thesis research (October 1993), my work has focused on the behaviour of artificial radioelements firstly in the geosphere and then in the biosphere. Research in these domains must directly or indirectly provide answers to very strong societal concerns relating to the consequences of artificial radioelements on man and the environment. The artific...

A containment spray system is used to mitigate the source term from building environment as part of severe accident management actions. Tellurium one volatile fission products and many tellurium isotopes decay into iodine, which causes a threat public due its radiotoxicity build-up in thyroid gland. The removal efficiency model against species formed under conditions was investigated with exper...
