  • 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 ...

  • Why is there no effective real-time Continuous Radiation Monitoring System?

    Japan's disaster has raised many questions regarding safety of the public. It has served as a wakeup call to the agencies tasked with protecting the public. Not least of these questions, but certainly the most far-reaching is the question of the safety of nuclear power and radiation contamination of air and water. Way back when nuclear power was first established, in the 1960s public opinion was ...

  • Role of radiobiology for radiation epidemiology using for radiation protection

    The problem of the application of radiobiological data for radiation epidemiology and radiation protection is considered. The causality of epidemiological consequences quite often cannot be established without radiobiological basis (Bradford-Hill epidemiological criteria). A number of epidemiological uncertainties can be removed with the radiobiology (uncertainties in a dosimetry, effects of the ...

  • The protection afforded by vitamin D against low radiation damage

    Our general understanding and appreciation of the multifaceted protective actions of vitamin D have recently entered a new era. It is now becoming recognised that its most active molecular form, 1,25-dihydroxyvitamin D3 (also known as calcitriol), may offer protection against a variety of radiation- and otherwise-induced damages. As will be discussed, vitamin D carries out its protective actions ...

  • ATR-dependent bystander effects in nontargeted cells

    Ionising radiation-induced effects in nontargeted bystander cells may play an important role in low-dose cancer risk. Here, we briefly review the experimental systems used for bystander studies, the initiation and intercellular transmission of bystander signals and response mechanisms in recipient cells. Recent evidence that implicates the histone 2A variant X (H2AX) and the deoxyribonucleic acid ...

  • Documented optimum and threshold for ionising radiation

    A concept of the complete dose-response curve of ionising radiation will allow us to live in harmony with this ubiquitous agent. Convincing data show ionising radiation is essential for life. Ambient levels of ionising radiation (about 2 mSv/y without medical and cosmic radiation) are adequate for life but insufficient for abundant health. We live with a partial deficiency of ionising radiation. ...

  • 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 ...

  • Re-examining the health effects of radiation and its protection

    The health effects of radiation from atomic explosions in Japan were completely different from those due to radiation from the Co-60 contaminated apartments in Taiwan. The sudden exposure to acute radiation in extremely high doses killed Japanese people, and harmed the survivors in lower doses as shown by increased cancer mortality, especially the leukemia based on the LNT model. The chronic ...
