Radiation levels (moved posts) - Stansfield123 - 2015-09-03 Zgarbas Wrote:Sometimes they're right, sometimes wrong, but a full working picture is simply impossible to obtain if you do not already have a background to support it. I wasn't trying to insult anyone, it was a response to Stansfield's comment that omg anyone who did not google the same things that I did is an idiot, you can learn science in 2 hours .I heard your argument before. Not in a chat about radiation, but about evolution. Religious lunatics who argue against evolution invariably complain that I can't possibly dismiss their Intelligent Design "science", because I don't have a Ph.D in evolutionary biology. But I can. Because you don't need a Ph.D to recognize junk science. You just need to know what actual science is. The anti-nuclear movement, just like Christian fundamentalism, is a propaganda machine. They use the same exact tactics, and they are very easy to recognize to anyone who prefers facts to meaningless philosophizing. Science is based in empirical evidence. Every hypothesis is verified, and in the absence of empirical proof, dismissed. Pseudo science refuses to hold itself to that standard, and instead holds its critics to the standard of "go ahead, prove me wrong". Or "I'm a scientist, so whatever I say is science". That is exactly the tactic the people pushing the "we can't know for sure if there are or aren't any victims, because the data isn't accurate enough" argument are using. It's not science. It's an arbitrary proposition that kinda sounds sciency, backed up by zero empirical evidence, that people who think science is "whatever self proclaimed scientists say", buy into. Radiation levels (moved posts) - Stansfield123 - 2015-09-03 bertoni Wrote:It's easily verified with enough data in support of it. How could it not be verifiable? It's a simple and measurable phenomenon.Because it's a statistical argument. Statistics are only as accurate as the size of their sample size. There aren't enough people exposed to low level radiation, to make for a large sample size. Junk statistical analysis is a tactic that's been used since the beginning of the environmentalist movement, by the way. Here's the simplistic description of how it works (if you don't like my simplistic example, and want to get technical, read the WHO report I linked to instead): Statistics always allows for a natural variance (the smaller the sample size, the bigger the variance). Let's say there are 13.5 people out of a 100,000 getting thyroid cancer in Belgium in a year, and there are 13.6 out of 100,000 getting it in France. Someone who wants to argue that French cheese causes cancer will take that difference, and declare that French cheese just gave 60 people cancer. But a statistician will point out that no, sorry. Belgium is a tiny country, not that big a sample size. That 0.1 drop compared to French thyroid cancer is just natural variance from the mean, not any kind of statistically meaningful difference. Similarly, when the World Health Organization, which employs reputed, established scientists, says that they foresee no statistically meaningful increase in cancer rates in the Fukushima area, what they mean is that there will be no statistically meaningful evidence for the arbitrary "linear no threshold model" proposition. It's an unverifiable proposition. Pseudo science. Tzadeck Wrote:I found a few sources putting the number of 'suspected' thyroid cancers among the normal base level as 16 (a jump from 59 to 75), with only 33 of the 75 total being confirmed as cancer.Thank you. There you go. Precisely the argument I described above. People latching on to statistically insignificant variation as "evidence". I bet I could find a city in France with even more cases, thus providing even stronger "evidence" that French cheese is worse than a nuke meltdown.

Why do you say it is not verifiable?Because that data doesn't exist. Nor will it exist in the future.

It's an arbitrary proposition that kinda sounds sciency, backed up by zero empirical evidence, that people who think science is "whatever self proclaimed scientists say", buy into.You have this exactly backwards. No decent scientist makes absolute statements like "we know for sure". It is always preceded by phrases like "the data suggests..". There's even a principle called underdetermination that essentially says that no theory can be proven, only disproven.

Every hypothesis is verified, and in the absence of empirical proof, dismissed.There are a number of books that have been written (and basically the entirety of 20th century science happened) since logical positivism was dismissed as functionless prescriptively, and inaccurate descriptively. Basically all of post enlightenment thought, and all modern science. It's worth reading some of what has been written, since Comte's idea about what science consists of were dismissed. Radiation levels (moved posts) - scooter1 - 2015-09-04 There is a movie from 1987 called radium city about the young women hired to paint watch faces. Close access to radium really did a job on the workers. The subsequent government "health reviews," propaganda, and clean up efforts are shocking. Watch the on-site interviews in the 1980s of the US federal government "clean-up." A lot of the laborers are moving ground-zero debris, just wearing tee-shirts and jeans. One of the local activist shows his Geiger counter in action, claiming a lot of ground-zero debris was just scattered to a variety of local dumping grounds. That was not too long ago! .be Radiation levels (moved posts) - bertoni - 2015-09-04 Stansfield123 Wrote:That's your opinion, and it might be true today, but it might be false tomorrow. "Never" is a long time. I would say that we might or might not have enough data yet on low levels of radiation exposure, but your statement about "unverifiable" is simply wrong.bertoni Wrote:It's easily verified with enough data in support of it.

Radiation levels (moved posts) - Tzadeck - 2015-09-05 "It is scientific only to say what is more likely and less likely, and not to be proving all the time 'possible' and 'impossible'." -Richard Feynman Radiation levels (moved posts) - Stansfield123 - 2015-09-05 yogert909 Wrote:Well, your statement is unverifiable too isn't it?Which statement? That claims of people dying from the Fukushima accident are not backed up by evidence? No, that's perfectly verifiable. All you have to do is ask the people making the claims to provide the evidence. When they don't, then you will have verified that their claims are not backed up by evidence. The burden of proof is on the people making the claim, not on the people disputing it. You're attempting the ol' "prove God doesn't exist" argument. See my point above about the anti-nuke crowds using religious fundamentalist tactics. Tzadeck Wrote:"It is scientific only to say what is more likely and less likely, and not to be proving all the time 'possible' and 'impossible'."Yes, but likeliness isn't the result of a poll among self proclaimed scientist, or random guessing. It's the result of the evaluation of actual evidence. There is zero evidence for the linear no threshold model. Inferring likely victims based on that nonsense isn't science. Richard Feynman would be the first to tell you that. Based on the actual evidence (what we know about the results of medium level radiation exposure of the type only the workers at the plant were exposed to), the most likely number of victims to this accident is zero. The second most likely, but significantly less likely number is one. Two or more, on the other hand, is extremely unlikely. 400 is in fact an impossibility, since less than 200 people were exposed to radiation levels that are known to be harmful. Radiation levels (moved posts) - Tzadeck - 2015-09-05 I've read literally every book Feynman wrote, including his textbooks, and watched every major interview and lecture of his made public. So, I don't need you telling me what he would or would not say; plus, in fact, it's rude to put words in the mouths' of the dead. I also have a better grasp of what science is than you, so if you could be quiet about that too, it would be great. I'm already aware that you think you understand science better than me, half because you don't really know what you're talking about, and half because you keep assigning beliefs to me that I don't hold.

Scientists and doctors who actually have backgrounds in this area say otherwise. Radiation levels (moved posts) - Zgarbas - 2015-09-28 So this was published recently. Late cite is better than no cite. Quote:Radioactive iodine affects the thyroid immediately. Iodine-131 is short-lived with a half-life of 8 days, and I-129 has a very long half-life of 15.7 million years. Both would be readily absorbed into the thyroid gland, as iodine is used to make thyroid hormones. In the nuclear reactor, both are produced in comparable amounts, but I-131 affects the thyroid more seriously. An entity with a shorter half-life emits radiation more often than that with a longer half-life in the same chemical quantity. The distribution of I-131 in the environment is difficult to determine accurately, as it is short-lived.Anyway, my quip with the whole thing is not really the radiated area per se, and I'm not against nuclear energy in itself, but when it's in the hands of incompetent companies and governments which range from withholding information to outright lying on their reports, maybe they can't really be trusted with it? |
