Safecaster Ryan recently put on his heavy coat and took a trip to Antarctica, brining along a trusty bGeigie and took these readings – making it official that Safecast has measured all seven continents! Nothing scary or unexpected here – everything is around 40 to 50 cpm / 0.11 to 0.13 μSv –  but exciting to check off this accomplishment.
