Exposure to Ionizing Radiation in the Endovascular Era in a Secondary Care Center

Published on: 2019-06-24


The use of ionizing radiation (IR) for medical use has been increasing over the decades. In 1977 the International Commission for Radiation Protection established fundamental guidelines for estimating the features of stochastic or non-stochastic damage caused by IIn fact, IRs cause tissue damage through two effects. The deterministic effect (better defined non-stochastic tissue damage) is dose-correlated, so it has a threshold value below which there is no tissue damage, and vice versa the more the dose increases and the greater the damage is. Its effects are verifiable in a short-medium time interval (e.g. radiodermatitis and non-tumour skin diseases, cataracts, infertility). The stochastic effect, on the other hand, is not dose-correlated, does not present a threshold value and is related to the mutagenic effect and to the risk of inherited transmission of the mutations induced by IR. The stochastic effect can occur even decades after the exposure, and therefore in the medium to long term.
