For those in CO, you might not remember the similar Rocky Flats fiasco.

The court cases had such funny stuff as overturning a jury verdict on appeals as "the judges wrote that under the law, the presence of plutonium on properties south of the Jefferson County plant, which closed in 1989 for safety and environmental reasons, at best shows only a risk — not actual damages to their health or properties."

https://www.denverpost.com/2010/09/03/appeals-court-tosses-j...

These days, the site hasn't been tested in over a decade, in an area known for top soil erosion. And now more and more houses are being built immediately adjacent, with no warning to the homebuyers that this used to be a nuclear waste superfund site.

On the 'plus side' they at one point tried to get rid of the plutonium waste by combining it into a slurry and injecting it into the ground, which left us with some of the first data on how hydraulic fracturing can cause an increase in earthquakes.

This happened quite a while ago, but similar things are still going on today. Recently, I was considering a job in Pennsylvania, which unfortunately was several miles from the Marcus Hook Sunoco refinery (which has been in operation since 1902). It was recently fined $750,000 for "illegal modifications to equipment that allowed tons of potentially hazardous gases to be released into the air over two years." ...

"According to DNREC, the flare was modified at some point to receive gases from multiple sources throughout the Marcus Hook side of the facility, although no permit for those changes was ever sought by the company."

Those gases included hydrogen fluoride among other things.

This (rocky flats) is the only case where on federal agency (FBI) raided another (DOE). It's a fascinating and terrifying story. Many of the employees who worked there died terrible drawn out deaths from radiation exposure during their jobs without any support. They just had 50 gallon oil drums of radioactive waste sitting in the open to the elements with visible rust holes in them for decades. They had multiple plutonium fires due to the buildup of plutonium dust in the air handling systems of the glove boxes which were supposed to contain it. They had manual machinists manually operating machine tools, mills and lathes, located within glove boxes to make the parts for the triggers. Also, on the less scary side they developed amazing ultra high speed film cameras to record the trigger explosions.

Which is a good story to tell all those techno-naive who go on about the safety of modern nuclear reactors and such (it's always past designs that are at fault)...

When there's money to be made by cheapening out (on construction, safety, disposal, testing, quality of employees, etc), whether the risk to others (and sometimes even to self), some people will cheapen out.

Add human error to that, and it's better if the whole thing happens to some old-style electricity factory, and not to one whose waste needs safe storage for decades, and an accident can kill hundreds of thousands.

If anything, that would be an argument against using coat factories too -- not an argument in favor of nuclear factories.

That said, the whole comparison that makes it as coal factories produce "more radioactive" waste, is based on comparing with "normal" nuclear factory emissions, under their 'theoretical' operation. Not the total long term potential, when one includes catastrophes, breakdowns, lousy waste containment and disposal, or the mafia just throwing it in the sea in the calculation.

I bought a home in Candelas knowing all about the rocky flats incident.

While the home builders are certainly not forthcoming on details of the incident, the site you linked to is packed with scientific inaccuracies and fear mongering.

I personally know workers who performed the cleanup, and also have reviewed health data which shows zero increase in cancer in the entire area for the 30 years since the last incident.

People like you are why I moved here. The houses are cheaper because of the reduced demand than they otherwise would be.

I'm on a phone, but later I will post a thorough debunking of the candelas glows site.

The problem with that approach is that the ground isn't radioactive at all, and the commenter fell for disinformation on a local antinucleaer hippy website. The houses were built upwind and uphill from the site, and the EPA, state, and local governments have all hired independent third parties to test for contamination. There is none. The area is now a wildlife refuge, and there is no trace of health effects in animals in the area. I bought a home there after investigating the data myself for over a year. I have a wife and two kids, and would never put them at risk. The amount of radiation Colorado residents are exposed to from the sun and ground minerals dwarfs anything from Rocky Flats. There is zero data to back up the hippy claims. I work with data for a living, and have actually found cancer clusters in the US around refineries and chemical plants.

Tldr: a Geiger counter will show nothing here.

The scale of the craziness at Hanford in the 50s-60s is difficult to appreciate, or even to imagine. Many of us have taken a lab course in qualitative inorganic analysis. You know, where you dissolve a sample in nitric acid, precipitate with sulfate, filter, redissolve the precipitate, precipitate with sulfide, filter, and so on. Eventually you understand what metals the sample contained.

OK, so back in the 50s-6s, that's how they isolated plutonium from neutron-exposed uranium. After aging in water for a few weeks, levels of short-lived fission products were low enough that humans could manipulate the stuff, behind several feet of steel, lead and concrete shielding, without immediately lethal radiation doses.

But then, what they did was dissolve this shit in hot nitric acid, in huge steel vessels. With clever mechanical manipulators. Even after aging, however, levels of xenon-133 and iodine-131 were still quite high. And where do you think they went? Up a stack, of course. What else? Abbeit through shielded pipes, to protect workers.

But you know, they could only dissolve when the wind was blowing fast enough. Because otherwise, the cloud of xenon-133 and iodine-131 overhead would inflict dangerous radiation exposures to workers. They released a lot:[0]

> The formally classified report Dissolving of Twenty Day Metal at Hanford states that Hanford officials initially planned to release approximately 4,000 curies of iodine-131 and 7,900 curies of xenon-133 but ended up releasing in actuality 7,780 curies of iodine-131, along with 20,000 curies of xenon-133 into the surrounding area's atmosphere within a seven-hour period. [1] In comparison, the March 1979 Three Mile Island accident released between 15 and 24 curies of radioactive iodine.

But hey, at least they didn't dissolve on days when the wind was blowing west toward Portland or Seattle. Mainly they nuked local subsistence farmers. Iodine-131 has a half-life of just eight days. That's short enough that levels in commercial milk are low enough, given all the delays from feed to cows to stores. But if you lived near Hanford then, and your kids were drinking milk from your own cows or goats, they got dangerous iodine-131 doses to their thyroids.

Wait, for real? I have zero training in handling fissile material, but I didn't think any significant level of radiation could make it through that much shielding.

cocoablazing 157 days ago [-]
There are rooms in some of these facilities that have been known as infinity rooms because no readily available radiation meter would not saturate in them.

The radiation field of a freshly removed power reactor fuel element is so strong that you couldn’t run past it fast enough to survive the dose.

gascan 157 days ago [-]
I fully understand direct exposure can be lethal nearly instantly.

It looks like what I didn't understand is radiation-blocking of a material (lead, concrete, water) is actually a decay function (half of the radiation makes it through X feet) rather than an absolute function (no radiation makes it through X feet).

In other words, given an infinitely radioactive source, you would require an infinitely thick lead barrier to protect you.

Really, I should have guessed given everything else about radioactivity is the same way.

mirimir 157 days ago [-]
Right, it's just like transparency for visible light.

But many of the fission products in neutron-exposed uranium emit high-energy gammas. And even lead is somewhat transparent.

Also, from what Google tells me, those "infinity rooms" at Hanford are probably contaminated with plutonium-239. That's an alpha emitter, and alphas (helium-4 nuclei) are pretty easy to stop.

mirimir 157 days ago [-]
As I said, people probably can't imagine :)

OK, consider a tall gantry crane on wheels.[0] Now imagine a plate, several feet thick, with layers of steel, lead and concrete, suspended below the rails. With a cab on the top, and no line of sight through the holes for the cables.

Before people start criticizing nuclear power. This story is about the Hanford Site. This is where they exclusively made plutonium for bombs, starting from the Manhatten Project. It’s a very complex situation with waste all over the site for a number of reasons, some of them really bad (aka management incompetence, government outsourcing of responsibility, etc), some of them sort of understandable (hey Joe, it’s 1945, we don’t know much about this shit but it can’t possibly hurt anyone if we bury over there in this vast wasteland. Don’t worry we’ll remember where it is... doesn’t).

My primary concern with nuclear power is the human element. For which we have a long and well-demonstrated history of limitations that don't match corresponding requirements.

In other words, we are creating something human history -- as well as contemporary events -- demonstrate we do not have an enduring ability to manage.

As they say, we can't put the genie back in the bottle. But we can perhaps do something to limit scope, particularly where alternatives are developing that are safer and, sliding down the development cost graph, more cost-effective.

P.S. I'll add that, until we can manufacture elements (more fully), I prefer to keep these limited resource available for potential future use, when we have acceptable alternatives -- for me, now, meaning solar, wind, hydro (all forms of solar energy, essentially).

Who knows what need we might have of them, in the future? What if really going to space requires them in significant quantity, but we burned them all up on street lighting and casinos? ;-)

(Wouldn't it be ironic if further sources were in space, but we didn't have enough to get there?)

I'd guess the latter. The way half-life works, the stuff that's dangerous to you as you walk around quickly decays and stops being dangerous.

The problem is with long half-life (and thus low-radioactivity) elements that sit on the trees, get mixed with soil, and thus eventually end up in ground water and local food chain. You might be able to walk around a disaster site safely in relatively short time after the event, but I wouldn't try growing anything there.

Interesting link, thanks. It looks like the readings are just along a major roads in Los Alamos?

I had figured there must be some independent monitoring here, because many retired nuclear engineers live in the area of the community by the cleanup.

With the history of the lab here, there are many sites that are contaminated, but most of them are within the lab bounds. Of course, dust doesn’t respect a fence. There have been some worrisome incidents, like when a water pipe burst in Los Alamos and sent water through an unregistered historic buried dumpsite that contained nuclear or toxic materials.

I looked into rented a workshop across from an empty field with the fence around it, and looked into the history of the site. It had been the waste dump it for the first several years of the lab during the Manhattan project. It turned out they had cleaned up the site a few years ago. Would I have been exposed to any radioactive or toxic and dust if I had been there during that time? Who knows. It’s not clear if they would’ve told me if I was. At the end of the street there was a milling building for uranium, plutonium and beryllium and the water treatment facility for the site, which poured all of the water straight into the ground. They’be been cleaning that up recently.

In my own work, I generally prefer to leave toxic debris undisturbed until I am ready to deal with it safely. Like asbestos, it doesn’t harm you when it’s sealed and undisturbed. It’s often worse to clean it up poorly than to leave it there.
