If your definition of "reasonable" is "one millionth" you'd be right, but also perfectly unreasonable. There is such a thing as natural radioactivity, it is everywhere. And if you demand that "artificial" radiation must be less than 1/10.000th of natural radioactivity in the worst contaminated areas to be "reasonable", then you suffer from a gross form hubris. Your claims about Iodine-129 neglect to mention that is has 1/1.000.000.000th of the activity of I-131.
This statement is confusing. Regardless of the activity of the radioisotope, the issue is not radioactivity in the environment it is the release of radioisotopes *into* the environment. They didn't exist naturally, they are mutagenic to life and cause cancers to gestate when they are inside a living being.
This is further compounded by the fact that Iodine is highly mobile, most of all, it is water soluble. This means that it will be dispersed in the environment at a much greater rate than it will be concentrated in humans. In fact, it is not even detectable around Fukushima Daiichi.
That's not right. The water solubility and the fact that it is a micronutrient analogue will mean it actually concentrates in the foodchain. This is called bio-concentration because the radioisotope presents to a metabolism as something it can use. On uptake it is incorporated into the biological systems in the body and becomes organically bound. It's alpha, beta or gamma emissions are absorbed into the surrounding tissue and depending on the energetic levels of the radio isotope causes a cancer to gestate. In humans this process takes about 6 years.
You also neglect to say that the total radiotoxicity of all longlived fission isotopes is less than the radiotoxicity of the natural uranium before it went through the reactor. It is LESS than what was naturally there anyway. I know you don't care about such facts, lots of other people do.
Which longlived fission isotopes? pu-239 is a long lived fission isotope and it is highly toxic. It presents as an iron micronutrient so it also bioconcentrates readily, it's chloride is highly soluble and it's oxide is toxic when inhaled. Oppenheimer's research found it was toxic to humans in concentrations of 1-10 micrograms.
So yes, other people care about such facts. Can you clarify what you mean?
Your body is full of potassium-40, carbon-14, thorium, uranium and their decay products. If you're so scared of radioactivity that you must demand Cs-137 to decay to one-millionth of the current concentrations before you feel safe, then go commit suicide. There is no place in the solar system that will satisfy your demands. You, sir, are a lunatic.
That is not relevant. At issue is radioisotopes, not radiation and it is completely valid to try to prevent Nuclear Industry effluents into the environment because they are toxic and mutagenic. I'm not so afraid of radiation however I think it is completely sane and rational, to be concerned about radio isotopes acting as nutrient analogues in the foodchain as they a factor that affects human health.
At the same time, your original point re WASH-1400 is interesting. I'm not sure if it is one I've read and I commend you for highlighting it. So whilst I don't agree with what you have said here, on points of fact, I think the polarization of this debate has been destructive and hasn't really led to an increased level of understanding of the issues that matter.
