If you read the article I linked to, you'll see that this is not talking about nuclear 'accidents', this is policy.

It goes on to say: "In a dossier passed to The Sunday Times, Lyall claims: oHigh-level radioactive waste was washed down drains intended for low-level waste. This liquid went into effluent pits which were then flushed into the open sea, sometimes on an incoming tide. oRadioactive materials were handled without appropriate protection. Two workers who were contaminated later died of cancer in their forties. oEffluent samples were collected for analysis using a wellington boot on a piece of string because sampling machinery was "a heap of rust".

    "One of the first discoveries of radioactive material on the public beach next to the plant was "covered up".

    "Radioactive containers left in dumps were not marked properly, leading to confusion over what they contained.

    "A dumping pit used for years for "high-level" waste disposal was redesignated to be used as a temporary store for less hazardous material. Lyall had intended that his account should come to light only after his death. However, continuing concerns about the health risks from contamination around the nuclear plant have persuaded him to speak out.

    "There have been so many lies told to con the public about Dounreay that I feel I must put the record straight," said Lyall.

    "This contamination (said Lyall) is a legacy being left for my children's children. It is an absolute disaster. They are talking about prosecuting these people. They deserve execution, not prosecution. This was people's lives they were playing with. They were acting like nuclear cowboys."
