Can any one 'loan' me a copy of: "Cave air ventilation and CO2 outgassing by radon-222 modeling: How fast do caves breathe?" by Andrew J. Kowalczk, Philip N. Froelich in Earth and Planetary Science Letters Volume 289, Issue 1, Pages 209-219, 2010?

many thanks in anticipation

I'll send you a copy I downloaded from sci-hub

many thanks for that Dave.  I had not realised that this 'free' source existed.

In Tome2 there is a part about radon.

Thanks Leclused.  In fact the second party does have short summaries in English so I can get some idea of the content.
