Sorry, but you're wrong. I took some radiation safety classes, and the main point I got from that is that "it depends". For example, alpha- and beta-radiation are often more dangerous than gamma, because gamma is easier to detect and measure.
People often focus on "radiation" part forgetting the "contamination" part. You can literally walk into the Chernobyl reactor active zone today for up to 2 minutes. But you cannot produce any food in soils around it for thousand years. And there's dozens of dangerous isotopes, each one accumulating and affecting human tissues differently.
Public generally only knows about Geiger counter. Yes, it will scream if everything is FUBAR, but it's useless for estimating safety of a food product.

(The context here is not walking down some road and getting bombarded with particles: but about the storage of industrial material and the risks it involves. Yes, stuff gets shot out at >300 years: but it's not just lying around randomly.)
- blibble 1y agoit's fine as long as it doesn't get out of its flask which it will do eventually, if it's left out in the open it needs to be buried reducing the volume via reprocessing helps assuming you can do something with the 97% of "useful" stuff extracted (which the UK has mostly failed at, and now stores it in a warehouse)
- 74B5 1y agoAnd then eventually, water seeps in. Like in the german Asse II mine, that is planned to be evacuated, which will be a major challenge. https://www.bge.de/en/asse/short-information/history-of-the-asse-ii-mine/ https://www.bge.de/en/asse/short-information/history-of-the-... It might be true that nuclear power produces less waste but we have to consider the scales of global energy demand, multiply it by the time scales of nuclear waste to reach what threshold exactly? When and how would nuclear waste become a problem. Would it take ~200 years like the industrial revolution with CO2? Would it be okay if it where 300 years? or 500? What do we do, when background radiation is rising from ground water and soil? Switch back to natural instead of green energy, hoping the next millenias will be fine? I dont think nuclear power is a solution. It can be step in an energy transition strategy, but no solution.

Never. If there is ever "too much" of it we reprocess it as per OP article to remove the "non-usable" stuff and burn up the rest.

- deepsun 1y agoWhy, if it's in sealed casks underground, than yes, gamma is the only thing to worry about. My whole comment was about nuclear waste danger and its associated costs, not about danger of an non-compromised waste storage facility. Sorry, I don't have a Twitter account to read the posts, but they look like my point exactly.

- roenxi 1y ago> But you cannot produce any food in soils around it for thousand years. Is that actually based on some sort of science though, or is it the same woolly thinking as the linear-no-threshold modelling that was popular around the time of Chernobyl? What are the actual risks here and how does it compare to low exercise or the typical amount of air pollution in a large city?
- tehjoker 1y agoafaik LNT is correct last time i looked into it. LNT had to be proven as powerful agencies much preferred the hormesis hypothesis because it let them off the hook.
- gregbot 1y agoLNT has never been established and probably never will be. It is still used in some contexts for conservative safety analysis. Places with multiple times typical background activity do not have measurably higher cancer rates.
- tehjoker 1y agoBEIR VII still supports LNT. There's some criticisms, but it seems like a pretty safe guess that just because the uncertainty climbs at low doses it's not just a straight line projection from the closest easier to ascertain value. Maybe some people are better at DNA repair, but some people have DNA repair defects too. The number of ion tracks is going to correlate with number of DNA breaks, and DNA breaks correlate with increased cancer. https://www.epa.gov/radiation/blue-book-epa-radiogenic-cancer-risk-models-and-projections-us-population#getacopy https://www.epa.gov/radiation/blue-book-epa-radiogenic-cance...

- deepsun 1y agoYup. And managing nuclear waste is not really a big problem that needs immediate solution, if ever. Shoving it deep underground seems to be the optimal way for the next thousand years. So there's no need in recycling really.
