Soooo after watching through the videos, they mentioned the name of the place I was thinking of (forgot the name again drat! Oh well ) and pointed out most of whot I already knew. Remembered a few other things I should've mentioned earlier as well.
Overall, not surprised they didn't find much... we know there's a background radiation in the world normally anyway. Obviously, yeu have to have some method of defending against such on a regular basis. This would mean that the body is capable of fighting off, absorbing, or disposing of significantly more radiation than we normally receive in a regular time span. This would also mean that it's only after we cross that threshold of how much the body can absorb, do we reap any negative effects.
Now, obviously there's not much radiation from whot we receive from sunlight, yet it's enough to cause skin cancer... that brings us to something else I should've mentioned earlier, and wasn't covered in the videos.
There's multiple forms of radiation. It's not just "radiation" as a blanket statement. Some forms require very massive doses to be directly ingested to have any effect. Some forms can't even pass through paper, let alone skin. Most radiation can't even get past something so simple as clothing.
Certain types are exceedingly dangerous and can kill yeu with relatively little doses, as they pass directly through yeur body and pretty much anything yeu're wearing.
Alpha radiation is generally harmless, and can't even get through clothing; beta radiation may make yeu feel ill if yeu directly consume it but isn't likely to cause much harm if external. Gamma radiation can go pretty much through yeu, one end to the other, and doesn't slow down without significant dense shielding like lead.
There's cosmic radiation as well but I'm not sure where that stands off the top of my head, other than probably being either equivilent to or stronger than gamma.
But yeah, most forms of radiation aren't that dangerous, especially not in low amounts over prolonged times.
Getting a large amount in a short burst, however, will cause significant issues, since it'll overload the body's ability to compensate.
It's a poison, like any other, think of it like alcohol. If yeu have a little alcohol, very small, trace amounts, yeu get virtually no negative effects at all. Yeu can have a sip of wine every day and not get drunk and be able to drive just fine and won't even remotely show up on a breathalyzer test or whotever if yeu have something like 2 ounces a day.
Now pump that up to 10 days worth in one go, 20 ounces at once suddenly makes a noticeable difference, and yeur body isn't able to ditch the stuff as fast as yeu feed it. The effects, however, are still restricted by body type; someone who's larger and weighs more will generally hold liqueur better. Same with radiation, since there's more skin to go through.
And then yeu can compare exposure to a nuclear bomb to just being equivalent to downing bottle after bottle until yeu pass out and die of liver failure XD
The body can purge itself of almost anything in tiny amounts, it just takes time is all. And naturally, we're capable of removing far more than we normally receive. Yeu can lift about 6X as much with yeur muscles as yeu normally seem capable of, but this's normally only triggered as capable during an adrenaline rush and such... the muscles would tear, the bones would break under the stress if it were done on a regular basis. So, rather than allow yeu to go to yeur limits, yeu're forced to use only a small fraction of whot yeu're truly capable of most of the time.
Same goes with absorption of poisons, such as radiation; yeu can accept alot more than yeu need to, in case it's required. But there is still a breaking point that can be reached.
I'm a little disappointed in the videos overall though... there were more than 57 deaths, and they weren't counting the people who checked the reactor immediately; just the cleaning crews afterwards. The vast majority of the people working at the plant at the time, including the idiot of a researcher who caused the whole mess in the first place, died from radiation sickness, so it's kind of obvious they're misrepresenting their numbers to some degree at least by not counting many individuals.
This kind of obvious gap in information calls the rest of their information into question, since they're picking and choosing to report only the things that match their desired outcome.
Even so, radiation isn't that big of a deal, but that kind of reporting doesn't help prove it to anyone.
