Several optimization approaches have been compared to optimally locate and power size the RBSs of a GSM network, in order to efficiently dimension the transceiver properties without exceeding radioprotection limits. Such optimization tools are embedded within a planning system where several modules interact, exploiting each other’s features. In particular, the optimum planning tools exploit the...

Cette étude, réalisée par l’IRSN (Institut de Radioprotection et Sûreté Nucléaire) dans le cadre d’une demande l’ASN (Autorité Nucléaire), concerne la caractérisation des formes physico-chimiques composés radioactifs rejetés les installations françaises fabrication radiopharmaceutiques au moyen d’un cyclotron. Elle vise à disposer meilleure connaissance sur effluents gazeux ces installations. é...

background: ionizing radiation causes deleterious effects on living system mainly due to oxidative damages of macromolecules and protein is the major target due to its abundance. the aim of this study was to investigate the effects of ionizing radiation induced changes in the molecular properties of bovine serum albumin (bsa) its secondary and tertiary structures, degradation, cross linking and...

abstractbackground: radioprotective effects of famotidine, an antagonist of h2 receptor clinically used for peptic ulcer treatment, was previously shown on radiation-induced micronuclei and chromosomal aberration in human peripheral blood lymphocytes and mouse bone marrow cells. this study was conducted to investigate radioprotective property of famotidine against radiation induced apoptosis in...

Abstract In vivo dosimetry for patient radioprotection is a real challenge concerning new radiotherapy treatments. this study we aim to develop dosimeter based on tissue equivalent material, flexible and adaptable the morphology in order perform complex irradiation beams. Here, report evaluation standard beams of highly composed silicone elastomer containing leucomalachite green as radiochromic...

La Commission internationale de protection radiologique (CIPR) a initié un examen et une révision du système radioprotection afin mettre à jour les recommandations générales 2007 dans la Publication 103 CIPR. Il s’agit début d’un processus plusieurs années qui nécessite collaboration ouverte transparente avec organismes personnes monde entier. Bien que le soit robuste efficace, il convient l’ad...

Silathiazolidine and metalladithioacetals (M = Si, Ge) have been prepared by the interaction of dialkyldichloro- or bis(diethylamino)dialkylsilanes and -germanes with 3-[N-(2- thioethyl)]amino-propanamide (WR-2529) and [1-thioethyl-2-(1-naphtylmethyl)]-2- imidazoline. The study of these compounds in the field of chemical radioprotection has shown a notable decrease in the toxicity and a rather ...

Despite their name, fibroblast growth factors (FGFs) are multifunctional regulators affecting a wide variety of physiological events. This review summarizes our recent studies on FGFs from mechanistic, physiological and application-oriented viewpoints. These include studies on the importance of βKlotho and glycosaminoglycans for the signaling of hormonal FGFs (FGF21 and FGF19); the physiologica...
