Differences between photon and particle radiations in terms of their biological effects： Evaluation and protection.Differences between photon and particle radiations in terms of their biological effects： Evaluation and protection.
We have opportunities exposed to many kinds of radiations, which are not only photon radiations like X-rays but also particle radiations such as proton, neutron or heavy-ion charged beam in medical treatments or space long-term missions etc. To understand radiation exposure risk about each of them is important in our modern society. Here, some examples to explore useful biological markers for evaluating radiation effects will be introduced. Particularly, differences in biological effects between photon and particle radiations might be possibly detected due to linear energy transfer (LET) or particle fluence. In addition, to explore radio-protective agents which are easily taken and have no side effects will be also shown. 第55回日本生物物理学会年会
