Not for the UK!
You are buying a charcoal kit, return envelope, and lab analysis of the charcoal. Unfortunately the envelope and lab forms in this kit are only for a Texas lab. Shouldn't be for sale outside the USA as posting it by air mail etc is not included in the price and will most likely ruin the test results anyway.

Cheap, and no other charges except shipping!
I knew all my neighbors had radon problems, but I waited way too long to finally test. The tests are very easy to run. Anyone can do it. Just follow the directions, enter all the information online, and ship the testers back to the manufacturer. It turns out my basement radon was quite high, and I did my own mitigation work, including covering up a sump pump hole, installing an active subfloor radon fan, and covering a basement storage area that was just crushed stone for the floor. I ran tests both before and after, and my efforts were rewarded by reducing the radon levels 20 fold. I don’t know how accurate they are, since I have nothing to compare to, but the results seem to be aligned with my work. The tests were also very fast, with results provided either the day the test samples were received by the mfr, or the day after. I can’t see any reason to pay extra for the “rush” results! You can also ship multiple test kits in just one FedEx box/shipment, which makes it quite economical.

This should not be sold outside of the US
It needs you send this back for lab analysis, which doesn’t work outside of US

Don’t buy if you live in Canada
Do not order this item if you live in Canada. I ordered this from the Canadian Amazon site. You are not able to use this in Canada.This is not mentioned on the info page. Also it came damaged. After I ordered, I was told it was not returnable. They agreed to return it, I tracked it, and they have received it, they won’t pay me my money back. Also Amazon customer service has closed the file and will not help, as noted on the info page, “ not returnable”. I have asked Amazon to take it off the website so no one else has this issue. 3 months later, it is still on the website. Do not support this company if you are in Canada. So, I’m out approximately $52 !
