July 2017

Archived from radmon.org - originally posted 19/07/2017 Blackpool UK - 19 July 2017 - Started around 17:00 BST / 16:00 UTC During quite a downpour today, 20mm in one hour. At it's peak was 65mm/h. Background radiation increased by approx 50% / 11CPM over a 2.5hour period. Not much by any means but still an indication there was some radioactive substance in the rain. Please note the Radmon graphs are UTC and the rain graphs are BST (UTC + 1) and so there is an hour difference between them. What caused it? I could be anyone's guess. Radon causing decay products to get caught up in the rain?
