The 21st L H Gray Conference, organised by the L H Gray Trust with the Society for Radiological Protection, brought together international experts in radiobiology, epidemiology and risk assessment, and scientists involved in diagnostic and therapeutic radiation exposure. The meeting — held in Edinburgh, Scotland, on 4–6 June 2008 — aimed to raise awareness, educate and share knowledge of import...

The question of whether very small doses of ionizing radiation really exert stochastic effects (i.e. induce harmful genetic effects, including cancer in a probablistic manner) has not been unequivocally settled. The much relied upon linear, no-threshold (LNT) hypothesis does not have convincing experimental evidence. As there are practical difficulties in generating data on genetic effects at v...

The use of particle accelerators in radiotherapy has significantly changed the therapeutic outcomes for many types solid tumours. In particular, protons are well known sparing normal tissues and increasing overall index. Recent studies show that tissue can be further enhanced through proton delivery at 100 Gy/s above, so-called FLASH regime. This generated very significant interest assessing bi...

The application of fast neutrons, negative pions or heavy ions will only provide an advantage for the radiotherapy of cancer if, in comparison with conventional radiations, e.g., X-rays, gamma rays and electrons, better depth-dose and collimation characteristics or specific radiobiological dose response relationships result in greater local control probabilities for tumours without increased fr...

In spite of the fact that radiotherapy is a common and effective tool fOr cancer treatment; the radio sensitivity of normal tissues adjacent to the tumor which are unavoidably exposed to radiation limits therapeutic gain. For the sake of improvement in radiation therapy, radiobiologythe study of the action of io...

We may not be able to make you love reading, but physical and chemical mechanisms in molecular radiation biology will lead you to love reading starting from now. Book is the window to open the new world. The world that you want is in the better stage and level. World will always guide you to even the prestige stage of the life. You know, this is some of how reading will give you the kindness. I...
