Radiation risk estimation models.
Cancer risk models and their relationship to ionizing radiation are discussed. There are many model assumptions and risk factors that have a large quantitative impact on the cancer risk estimates. Other health end points such as mental retardation may be an even more serious risk than cancer for those with in utero exposures.
متن کاملRisk of Radiation Carcinogenesis
Occupational radiation exposure from the space environment may increase cancer morbidity or mortality risk in astronauts. This risk may be influenced by other space fl ight factors including microgravity and e nvironmental contaminants. A Mars mission will not be fe asible unless improved shielding is developed or transit time is decreased. – Human Research Program Requirements Document, HRP-47...

متن کاملGreater risk from radiation?
adiation can harm cells even if they don't take a direct hit, according to a new study. Injured cells apparently pass on damage to neighboring cells through gap junctions. The report has raised a ruckus because it suggests that current safety standards may underestimate the hazards from low-level radiation exposure Although some scientists suspected that radiation damage might spread from cell ...
متن کاملRadiation Benefit and Risk Assessment
How much radiation does it take to cause our risk for an observable health effect to increase? Is there a level of radiation that is safe? How is radiation beneficial? The question of an effect occurring because of radiation exposure and the question of whether low‐ level radiation is safe are much‐debated topics. There are many thoughts on the answers to these questions, and suggested answers ...
