The pyramids have been up and stable longer than ten half lives of any radioactive isotope crated in a reactor'

The oldest pyramid was completed around 2650 BC so it been up for about 4,600 years.

The seven long lived fission products have half-lives ranging from 211,000 years ( Technicium-99) to 15.7 million year (Iodine-129).

 Completely wrong The oldest fission products are uranium and thorium with half lives in billions of years.

Uranium is what you put into reactor - it's not a fission product.
There are neutron flying around inside a reactor, and a neutron hitting a uranium nucleus doesn't necessarily cause it to fission but can get capture, which is how some of the U-238 in a reactor gets turned into Pu-239. That isn't a fission product either.
I've not heard that U-235 fission reactors produce thorium. People put Thorium-232 into U-235 nuclear reactors to "breed" thorium-233 which is fissile.

Iodine 129 et al are so un-radioactive you could bathe in them and be just fine.

Iodine-129 with it's 15.7 million year half-life, doesn't decay to Xenon-129 all that often, and it only emits a 194KeV electron (beta decay) in the process.
But you don't want to bathe in it. Iodine concentrate in the thyroid, and any 194keV electron can mess up your DNA. Shorter-lived radioactive isotopes of iodine are used to shrink over-active thyroid glands. There's a cancer risk, but not a large one, and hyper-thyroidism is disorder that it pays to treat.

Wrong again.

We in the UK should give thanks to Cockcroft's follies. We were damn lucky that his somewhat wacky stack filter idea prevented massive fallout when the carbon moderator caught fire back in 1957. Radioactive discharge would have been ~20x worse without them.

Not even as bad as Chernobyl, which was the same without the filters and 100 times bigger

Not remotely similar, as you would have been able to work out of you had read the link below.

Almost identical, in that a carbon fire in an unenclosed reactor spread nuclear material around. I know ALL about BOTH accidents . I read ALL the literature

And more importantly, I understood it.

Or think you did. The problem in the in the Chernobyl reactors wasn't just a carbon fire - while they did use some graphite moderator elements, and these did catch on fire - but a control failure which lead to a much higher fission rate than the cooling system could cope with, generating enough steam to blown the structure apart.

 Really you must be a relative of  Commander Kinsey.

The Scottish Wanker? Your grasp of reality really is remarkably frail.
