Oh, those fucking stupid people thinking about nuclear weapons and nuclear power plants at the same time. How could they make such an OBVIOUS dumb mistake? — Ever Wise
OK, so let's track what happened. First came nuclear weapons. They weren't a secret. Hundreds of them (a good sized war's worth) were being exploded in the atmosphere, every one of them blasting an isotope salad into the atmosphere, to be distributed by wind and water. All that went on from 1945 until 1963. After that, tests were conducted underground.
The concern about nuclear bombs didn't disappear in 1963, of course. We could just stop worrying about fallout from above-ground tests. Nuclear bombs remained in production until the late 1980s, when I think we all had accumulated something like 36,000 bombs.
The first Earth Day was 49 years ago--22 April, 1970. I don't remember it. I suppose it was about butterflies and pesticides, trees, flowers, and children. It probably wasn't about CO2 levels in the atmosphere. though acid rain was a known consequence of burning coal and oil. CO2 hadn't become a big issue, yet.
Nuclear power plants were on line were humming away by 1970. In 1970, though, people were still worried about nuclear weapons. They had not gone away. Then there was the 3 Mile Island accident, which wasn't so very terrible but the people were frightened, the way sheep are frightened when they see a wolf. The brakes were slammed on and not much new happened in nuclear power. But the plants that were operating continued on, pretty much.
Chernobyl happened in 1986. This was much worse than 3 Mile Island. This one blew up, blasting tons of radioactive material into the atmosphere.
People are afraid of plutonium, uranium; cesium 137, iodine 131, strontium 90, and lots of other isotopes that they had heard about during atomic testing. These and other isotopes came out of the Chernobyl blast. I suppose we could forgive people for thinking that a dusting of plutonium or iodine 131 is what killed the liquidators at Chernobyl. What killed people there were gamma rays -- harsh, penetrating, ionizing radiation. Workers brought to hospital from Chernobyl were themselves emitting gamma radiation.
About this time, give or take a few years, CO2 became an issue, and as a decade or two have passed, seems like the most pressing issue of the day -- no longer atom bombs (though they haven't disappeared), radiation from nuclear power plants (which haven't disappeared either). Those who have inquiring minds that want to know, are now aware of how exceedingly dirty nuclear weapons production has been. Suspicion might have continued to dissipate had not an earthquake's tsunami wrecked the Fukushima nuclear plant. Another melt down, another mess. Not to worry, the levels of radiation are not too much above background radiation. It's all being diluted, we'll clean it all up, everyone will be happy again, yada yada yada.
So, friends, we have more to worry about now. There are the still ticking atom bombs; all the nuclear power plants that haven't blown up yet, and all the CO2 that is clearly screwing things up. The Ozone Hole seems to be OK for now. Bees are disappearing, along with other non-honey bee pollinators, and that could be really bad. Human sperm counts are dropping around the world (about 50% since WWII). Childhood cancers--which were once a rarity--are fairly common now. Various chemicals being used resemble hormone molecules, and these look-alike chemicals are screwing up development of fish and humans (other animals too).
If there is a common enemy here, it's capitalists and state monopolists (USSR) that have always preferred to externalize the costs of their profit making by dumping the crap in the river, blowing it out the stack, burying it in holes (out of sight, out of mind), or just using the lumpen proles as a sponge to soak it all up.
