Traduction de «low radiation » (Anglais → Français) :

11. Points out that the technology based on backscatter X-ray scanning emits a low dose of X-rays and proposes therefore that this technology be avoided, as clearly any exposure to ionising radiation, however low, may have long-term effects on health due to the cumulative effect of radiation;

Focusing on the question of risks linked to exposure to radiation at low and protracted doses, research into radiation protection will consist of:

(da) improvements to building shells and structures aimed at achieving summer comfort at no or low energy consumption, such as technologies to control fluxes of heat and solar radiation (higher thermal insulation of walls, low emissivity and solar control glazing, ventilated roofs with radiant barriers), technologies for the connection of buildings to low temperature environmental sources in summer (coupling with soil through air or water circulation, night ventilation accompanied with increased thermal mass); improvements to building shells and structures aimed at achieving winter comfort (thicker walls, roof and basement insulation, w ...[+++]indow frames with low transmittance and low infiltration rate, low emissivity glazing);

New studies of the effects of chronic, low dose-rate exposures using the whole organism which measure the new delayed effects of radiation such as radiation-induced genomic instability (the appearance of mutations, chromosome aberrations, etc. in cell generations long after the initial radiation insult to the parent cell genome) and bystander effects (responses in the un-irradiated neighbours of irradiated cells. These should be done in conditions which approach the natural situation as closely as possible), for example in areas of hi ...[+++]gh natural background, in low background facilities and in the areas contaminated by accidental releases.
