Surely you have a credible, reliable, independently verifiable source?

The issues were covered in both of those threads, did you read more than just the first post?

why do you not post in the hard to debunk theories threads and can you address the issues I am raising ?
It's difficult to debunk conspiracies that are unfalsifiable, and since the people are already believing an unfalsifiable thing...it's not really my business to get up in their beliefs or faith. Something like this topic is easy, it literally has no foundation.
The issues you are raising are moot, because as is shown by Berkeley's data, there is nothing currently in the air. Also no evidence of a coverup whatsoever.edit on 10/23/11 by adeclerk because: (no reason given)

That's a nice opinion, brother, but it does not reflect the data. Given that both the EPA and Berkeley didn't find significantly elevated levels of radiation (independently of each other). Not much I can do to influence an opinion based on faith, I'm afraid.

I am not your sibling, nor will I ever be , it's a dna thing, now let's get to the facts:are HOT isotopes a factor in the valley of death calculation .
scientific consensus studies (e.g. CERRIE) conclude that the current ICRP risk model, despite being largely derived from studies of survivors of external radiation, adequately estimate the risk of hot particles i.e. internal radiation is no more dangerous than an equal amount of externally delivered radiation.[
CERRIE concluded there is no convincing evidence that the risks of internally delivered radiation differ from the risk projections derived from externally delivered radiation e.g. Japanese Atom Bomb survivors, and any differences between internal and external radiation are adequately accommodated by the established appropriate parameters (relative biological effectiveness, kinetic factors) in physiological models.
emphasis mine
Risk estimates are subject to several sources of uncertainty due to inherent limitations in epidemiologic data and in our understanding of exactly how radiation exposure increases the risk of cancer. In addition to statistical uncertainty, the populations and exposures for which risk estimates are needed nearly always differ from those for whom epidemiologic data are available. This means that assumptions are required, many of which involve considerable uncertainty.
In addition, because the exposure was to the whole body, the LSS cohort offers the opportunity to assess risks for cancers of a large number of specific sites and to evaluate the comparability of site-specific risks.
The use of data on persons exposed at low doses and low dose rates merits special mention. Of these studies, the most promising for quantitative risk assessment are the studies of nuclear workers who have been monitored for radiation exposure through the use of personal dosimeters. These studies, which are reviewed in Chapter 8, were not used as the primary source of data for risk modeling principally because of the imprecision of the risk estimates obtained. For example, in a large combined study of nuclear workers in three countries, the estimated relative risk per gray (ERR/Gy) for all cancers other than leukemia was negative, and the confidence interval included negative values and values larger than estimates based on A-bomb survivors (Cardis and others 1995).
emphasis mine
Studies of populations with occupational radiation exposure are of relevance for radiation protection in that most workers have received protracted low-level exposures (a type of exposure of considerable importance for radiation protection of the public and of workers).
For exposure scenarios in which various tissues of the body receive substantially different doses, estimates of risks for cancers of specific sites are needed. Adjudication of compensation claims for possible radiation-related cancer, which is usually specific to organ site, also requires site-specific estimates. Furthermore, site-specific cancers vary in their causes and baseline risks, and it might thus be expected that models for estimating excess risks from radiation exposure could also vary by site. For this reason, even for estimating total cancer risk, it is desirable to estimate risks for each of several specific cancer sites and then sum the results.
This is odd, why would nuclear plant workers have negative risk?
Forgive my continuing denseness, but this bit isn't quite clear to me. Specifically it's the final sentence which is a has me flummoxed.
ICRP has admitted that its model cannot be applied to post-accident situations. Fortunately the European Committee on Radiation Risk employs weighting factors to modify sievert-based doses for internal exposures. This won't cure the mess in Fukushima but it will mean better public protection.
The authorities apparently refer to the so-called standards of permissible or acceptable limits set by the International Commission on Radiation Protection (ICRP) and the US Nuclear Regulatory Commission as basis for declaring that exposure levels of the public are "small" and within "safety" limits and that significant risk of harm is limited to the immediate vicinity of the power plants. These standards, in fact, have been set to accommodate the interests of the nuclear industry and countries with nuclear weapons. The ICRP recommendations of exposure limits are not based on worker and public health criteria, but on value judgements with respect to the acceptability of risk estimates for what it sees as benefits of the activities. Since the decision makers, were either users of ionizing radiation in their employment, or are government regulators, primarily from countries with nuclear weapon programs, the vested interests are very clear.
Stockholm, 22nd April 2009. The recently resigned Scientific Secretary of the ICRP, Dr Jack Valentin (icrp.org), conceeds to Pr. Chris Busby, ECRR (euradcom.org) , that the ICRP model can not be used to predict the health effects of exposures and that for certain internal exposures it is insecure by up to two orders of magnitude. He also said that as he was no longer employed by ICRP he could agree that the ICRP and the United Nations committee on radiation protection (UNSCEAR) had been wrong in not examining the evidence from the Chernobyl accident, and other evidence outlined below, which shows large errors in the ICRP risk model.
Karl Morgan was an American physicist who was a founder of the field of radiation health physics. After a long career in the Manhattan Project and at the Oak Ridge National Laboratory, he became a critic of nuclear power and weapons. Morgan, who died in 1999, began to offer court testimony for people who said they had been harmed by the nuclear power industry.
“Nobody is talking about the fact that there is no safe dose of radiation,” Cabasso added, “One of the reasons Morgan said this is because doses are cumulative in the body.”
The National Academy of Sciences (NAS) published a report in 2006 titled Biological Effects of Ionizing Radiation (BEIR) report, VII Phase 2. NAS BEIR VII was an expert panel who reviewed available peer reviewed literature and wrote, “the committee concludes that the preponderance of information indicates that there will be some risk, even at low doses.”
The concluding statement of the report reads, “The committee concludes that the current scientific evidence is consistent with the hypothesis that there is a linear, no-threshold dose-response relationship between exposure to ionizing radiation and the development of cancer in humans.”
The ECRR risk model has been applied to the 3 million people living in the 100km radius of the Fukushima catastrophe. Assuming these people remain living there for one year the number of excess cancers predicted by the method is approximately 200,000 in the next 50 years with 100,000 being diagnosed in the next 10 years. If they are evacuated immediately, the number will fall by a significant amount. For those 7 million living between 100km and 200km from the site, the predicted number of cancers is slightly greater with 220,000 extra cancers in the next 50 years and about 100,000 being expressed in the next ten years. These predictions are based on the ECRR risk model and also the findings of cancer risk on Sweden after the Chernobyl accident.
2. The ICRP model predicts 2838 extra cancers in the 100km population. The eventual yield will therefore be another test of the two risk models…”

This coupled with the lack of data showing the "hotbed" of nuclear activity that you'd like to think exists completely disproves your "valley of death". I must ask, why are you still fear mongering over this? Why do you want it to be dangerous?

again you use a negative to try and prove something, when so may positives are present ...and IT IS NOT MY HOT BED THEORY...you do not use facts or scientific method. I observe out loud on SCIENCE ISSUES and clearly define when I am expressing my opinion otherwise.

about fear mongering ...hmm that was said way back in the beginning of the fuku thread but almost everythin to the letter I posted there has come true ...is it fear to assess the facts in an honest fashion?
