[Vo]:the Radiation Paradox

2012-07-24 Thread Jones Beene
In following up on a story in the Sci-News today, mention was made of the so-called Radiation Paradox. In fact there are two versions. If there is longer-term hope for the residents around Fukushima, healthwise, this could be relevant. A region around Ramsar, Iran on the Caspian has the highest

Many people in Japan think that low level exposure to radioactivity in hot springs is good for you. That includes many scientists. Hideo Ikegami thought so. There may be something to it. We are evolved to survive low, natural levels, so I doubt they cause much harm. Jones Beene

What is well know science today is thate unlike the radioprotection assumption, effect of dose is not at all linear without treshold. in fact any agression, like oxygen, chemican aggressors, heat, sun, radiation, might cause DNA error. if the dose is very low, the cell detect the error and launch

By the way, Ikegami also said that tests with tritium failed to show biological damage. They exposed various species to much higher concentrations than the safety rules allow for people, but the plants and fish seemed fine. Mike Melich says the radiation standards were more or less pulled out of

another detail I've heard recently is the importance of the dose flow, and not only the dose. fast dose flow will cause much more dammage, than regular flow of the same dose. this have been recently studied and published. it is not new data, but simply catching more attention than before.
