New Scientist Radon

A recent article in New Scientist (5th April) warns about the exposure to Radon that cavers could be subjecting themselves to.

"Researchers from University College Northampton and Princess Margaret Hospital in Swindon measured Radon in a popular system of caves in the Mendip Hills in Somerset. They found that cavers who spent just 40 hours a year underground could receive a radiation dose of as much as 4 millisieverts - four times the annual safety limit for members of the public recommended by the UN ..... Guides and instructors spending 800 hours a year underground could receive as much as 120 millisieverts five times the safety limit for radiation workers"  (Journal of Environmental Radioactivity vol 49, p235).  Worried cavers should read the article!

White Pit

A new entrance lock has been fitted to the cave as the intellectually challenged have been dropping stones down the entrance shaft.  If you were a previous keyholder either call on Tony Jarratt at Bat Products or contact Rich Long (the caving secretary).

Waterwheel Cave.

Following an act of vandalism in this cave, the access controller, Charterhouse Centre, Near Blagdon, BS40 7XR on behalf of Somerset County Council the landowner, have further restricted access to the cave.  The lock has been changed and the key will only be available via Charterhouse Centre as before.  In future, all visitors will be asked to fill in a log.  Further work on strengthening the lid, retaping sensitive areas and recording formations will take place.  This work will be carried out by Cheddar Caving Club under the guidance of CSCC/Charterhouse.  No novice groups, leader plus six members only.
