Berthold rays were a potentially lethal radiation type. One common effect was to cause living animal tissue to disintegrate. (TOS: "This Side of Paradise")
In 2385, Doctor Henglaar stated that subspace weapons and isolytic bursts caused both hyperonic radiation and Berthold rays. (Henglaar, M.D.: "Profit Without Honor")
