This prompted the NCA to revitalise the Radon Working Party which met again in March 1994. It was clear from the outset that all cavers must comply with the laws as presently framed. This is simply because presently there is no database from which to construct an argument in an attempt to achieve any change. Additionally, cavers also needed a document that clarified the situation for land owners as there are potential legal duties. The risk from radon must be put into context with all the other hazards involved in caving.
Some hazards are obvious and can be relatively easily assessed such as falling or drowning.
Others like Weil's Disease, are intangible and often precautions are taken not knowing if it is present or not. Radon is similarly intangible. Whilst exposure to it is just another of the hazards, this one must be seriously considered before being accepted. Calculations have been made to compare the relative risk of dying from lung cancer due exposure to radon compared to the risk of dying from other hazards whilst caving. These suggest that the risk from radon on a typical caving trip is less than that from the risk of dying from any of the other hazards.
