THE nuclear company Sellafield Ltd was today fined £75,000 after pleading guilty to breaches of health and safety law after two contractors inhaled radioactive contamination.
The prosecution follows an investigation by the Health and Safety Executive (HSE) into an incident on July 11, 2007, at the west Cumbria site.
Sellafield Ltd pleaded guilty to breaching Section 3(1) of the Health and Safety at Work etc Act 1974. The company was fined £75,000 and ordered to pay costs of £26,100 at Carlisle Crown Court.
The incident happened while removing radioactive contamination from an area of concrete floor in a room formerly used to sort and monitor material contaminated with plutonium.
A patch of concrete floor – believed to be contaminated with radiation from spillage some years ago – was being drilled prior to being removed.
Two contractors were drilling an area of the floor, under Sellafield Ltd’s supervision, when they were contaminated with plutonium by the dust produced from the drilling, some of which they inhaled.
There was no immediate impact on their health, but they received a significant radiation dose below annual dose limits.
The two workers were monitored, undressed and removed from the enclosure.
One contractor had widespread contamination on his PVC suit and while he was undressing two radiation air monitors outside the enclosed area were triggered. The enclosure was later found to be heavily contaminated.
