  • Individual radiosensitivity: a key issue in radiation protection

    Immunofluorescence that permits the detection of nuclear targets specific to DNA damage signalling and repair have completely renewed the approach of individual radiosensitivity. It is a concern in radiotherapy in which radiosensitivity is responsible for the development of adverse side–effects in normal tissues in absence of any mistake in the dose delivery. Furthermore, individual ...

  • Low–dose ionising radiation: scientific controversy, moral-ethical aspects and public choice

    The ethical issues of radiation protection are dealt with on a systematic basis. It is shown that the Linear No–Threshold (LNT) model of low–dose ionising radiation damage, being widely accepted, is still ill–founded. In everyday routine, the present regulation imposes excessive cost on society, effectively leading to loss, rather than to saving, of life. In nuclear emergency, compulsory ...

  • Measurement uncertainty

    The IAEA/WHO Network, through Secondary Standards Dosimetry Laboratories (SSDLs) designated by the Member States, provides a direct linkage of national dosimetry standards to the international measurement system (SI, for Système International). Through the proper calibration of field instruments by the SSDLs, these measurements are traceable to the Primary Standards Dosimetry Laboratories (PSDLs) ...

  • Risk evaluation model for radiation protective countermeasures based on fuzzy entropy weight

    On the basis of establishing a risk assessment index system, a model for assessing the risk of radiation protective countermeasures is proposed by introducing a fuzzy mathematics method and entropy weight theory, and the risk order of the radiation protective countermeasures is ranked by their entropy weight coefficients, which solves the decision problem of uncertain and fuzzy indexes in the ...

  • Changing views on ionising radiation-induced cellular effects

    Low dose and low dose-rate effects of ionising radiation (IR) are important issues in radiation protection. For these low exposures, radiation-induced double-strand breaks (DSB) and locally multiply damaged sites (LMDS) are considered very deleterious for cells, leading to lethality, mutations, genetic instability and cancer. However, recent results suggest that LMDS are much less frequent than ...
