I understand that a surprisingly large fraction of the Canadian population lives within 20 miles of the U.S. border. There might not be much health data elsewhere, regardless of how much Iodine-131 is in the environment. | |

| Sep 17, 2020 at 13:48 | comment | added | rob♦ | This takes me back to one of my very first scientist-like experiences. I was in elementary school and we were taking a quiz about how to read a color topographical map, and I sweated over the question “where is the elevation the highest” while I hunted for some hard-to-find white circles on the Colorado Plateau. When we discussed afterwards, the teacher asked that question and then said, in unison with the class, “Mexico!” — because Mexico was printed in a light grey “no data” color. I protested that the Rio Grande river probably didn’t run at the foot of a 14,000-foot cliff. | |
