Response to criticism of the paper titled 'Non-targeted effects and radiation-induced carcinogenesis: a review'.
Exposure to ionising radiation is clearly associated with an increased risk of developing some types of cancer. However, the contribution of non-targeted effects to cancer development after exposure to ionising radiation is far less clear. The currently used cancer risk model by the international radiation protection community states that any increase in radiation exposure proportionately incre...
متن کاملNon-Ionising Radiation Protection How much protection is enough?
Non-ionising radiation protection generally proceeds by establishing a dichotomy. Certain effects are regarded as established, and scientific bodies set exposure guidelines designed basically to prevent such effects. At low frequencies the principal such effect is induced electric fields in tissues, and at high frequencies is heating. For all other effects, regarded as not being established, tr...
متن کاملRBE and radiation weighting factors as applied in the context of protection of the environment from ionising radiation
It has long been recognized that the degree of biological impact on an organism resulting from a given absorbed dose of ionising radiation can vary depending upon the type of radiation involved. This difference has been experimentally quantified and reported as the “relative biological effectiveness” (RBE) of specific radiation types. RBE values have been measured for a variety of end points in...
متن کاملThe impact of high and low dose ionising radiation on the central nervous system
Responses of the central nervous system (CNS) to stressors and injuries, such as ionising radiation, are modulated by the concomitant responses of the brains innate immune effector cells, microglia. Exposure to high doses of ionising radiation in brain tissue leads to the expression and release of biochemical mediators of 'neuroinflammation', such as pro-inflammatory cytokines and reactive oxyg...
متن کاملNurses', physicians' and radiographers' perceptions of the safety of a nurse prescribing of ionising radiation initiative: A cross-sectional survey.
BACKGROUND A new initiative was introduced in Ireland following legislative changes that allowed nurses with special training to prescribe ionising radiation (X-ray) for the first time. A small number of studies on nurse prescribing of ionising radiation in other contexts have found it to be broadly as safe as ionising radiation prescribing by physicians. Sociological literature on perceptions ...
