I know of a hospital where the local university sends tracers with F-18 for PET scans in much the same way. Half-life of 110 minutes.

No postage needed in California, nor Massachusetts if I recall correctly. Does your state really make you find a stamp to vote in 2024? That sucks, sorry to hear that.

I would also like to see a similar graph for mid-term elections. Do the winners even get 10% of the eligible votes?
