And somewhat off topic, I don't login that frequently, so could someone explain what the M word is, and why it is so contentious:)

Minerals
There is a lot of aggro over them and as such its become something of a forbidden topic on here.
Some will put the lives of themselves and others at risk, break down gates, and literally fight each other over them. On the positive side some professional mineral dealers are very kind and put a lot of money into reopening places and then allow explorers in. Fortunately the latter outnumber the former.

Trouble with me is that I know little about them and have little interest hence my getting hot (no pun intended) over the shaft in the video with a rising main and what appears to be a clack (valve) box. The finest example I have yet seen is in Cwffty Western Shaft, north Wales. Industrial archaeology and photographing 'minescapes' is my thing. Beside digging places open and building more and more powerful lamps and then rushing underground to try them out.

Attitudes to experts on here can be cynical, one big problem nowadays is that there are too many people coming from somewhere else, this tends to generate mistrust.

Take care

Thanks Roy, I understand now. My field of research is mineral physics, a branch of mineralogy, and I have my own views of mineral collectors (that I shall keep to myself).>:(

yes and he still has your rope

Guess this is still a hot topic, no pun intended.

A collaborator of mine from the Immobilisation Science Laboratory at the University of Sheffield was investigating the degree of soil contamination at South Terras. He's away on holiday, but I will chat on his return and post a comment.

One of our senior health physicists has seen the video on youtube and read the paper. I am hoping to meet up with him next week. He has experience with radon monitoring in previous employment decommisiioning reactors. However, he made the point that handheld monitors give false readings and passive monitors are the recommended method of radon monitoring. When I get his feedback, I shall post.

The choice to enter, is of course, your own

your friend works on the absorption of isotopes through plants and bacteria ?

The radon daughters stick to the dogs fur, making everyone elses' passage more safe.
