You can google it. Technically, EVERYTHING in that general range on the table can occur naturally (possibly very, very rarely but it happens).

As I said, for practical quantities, it has to be man made. It occurs very rarely, and has such a short half-life that you just can't access any appreciable quantities in nature.

Your statements are in disagreement with statements the person who won the Nobel Prize in chemistry for man-made elements, and responsible for creating 10 of the man made elements, more that any other person. Again, I respect you, Rick, but this statement is incorrect per what Dr. Seaborg told me, first hand.

No worries. There are a variety of isotopes, some are more plausible in nature than others. Pu-238 in nature probably would require Np-238 to be created by a natural process involving deuterons and U-238... those are both readily available but I don't know what the required energy of the deuterons would be, might be rather high perhaps implausibly high.

I have a friend who does physics for RTG design, I'll ask her, Pu-238 would be right up her alley.

How/why'd you meet Glenn Seaborg?

TransWorld

My degree was in Chemical Engineering. I was a member of the national chemical sciences fraternity. Glenn was the student chapter advisor at Berkeley. We ended up as good beer drinking buddies at meetings. Been to his house. Knew him, and his wife, Helen.

When you find there are other isotopes of Pu on distant stars, you will be in agreement with what Dr. Darlene Hoffmann said to me 2 decades ago. She took over from Glenn, when he retired. But no Pu-238.

For clarity for others reading this, some Pu isotopes do clearly occur in small but detectable quantities in nature. We're splitting a fine hair re. Pu-238 .

I’d expand that, if you’re in any safety critical industry subject to testing, taking an controlled substance or CBD, you’re a f’ing idiot. Ricky Gates killed 16 while thinking train driving and smoking was acceptable.

Couldn't you have said all of this in a post with a word count of at least 1000+? You're really slippin'. Nonetheless, hard hitting and insightful as always.

I am sorry about your wife, and don't disagree with you at all. The problem, which isn't the point you were making, is that it's being studied very lightly by a narrow scope under more narrow regulators. So claims can be made as such just like the supplement market that is a not regulated by the FDA. I too had a family member with a disease that after some research had us giving them both cbd and thc. It helped symptom like you wouldn't believe but it wasn't a cure all and they later died of said disease. However, it improved quality of life 10 fold. The studies are starting to trickle out that cannabinoids should be used in more of a preventative form instead of reactionary to the disease that you develop. In cancer and certain neuro diseases taking cannabinoids help neuroplasticity and removing damaged cells from the body, and damaged DNA.

As a profession that is exposed to radiation a great deal, I would hope these studies help influence the FEDs as I believe CBD and other non-mind altering cannabinoids should be taken by this labor force to offset, even in the slightest bit, our exposure. Right now all we have is to eat well and exercise to keep the immune system at tip top. And by the looks of what I see in airport terminals not a whole lot of us are doing that.
