Members of a watersports club have voiced their concerns about radioactive discharges from Bradwell Power Station into the Blackwater Estuary.
The Stone Watersports Club, in St Lawrence Bay, has been established for 50 years and watersports run from the site include jetskiing, water skiing, wakeboarding and windsurfing.
But members are now concerned about metal casings surrounding spent fuel rods being dissolved at Bradwell Power Station as part of work to decommission the site.
Richard Peters, who has been a member of the Stone Watersports Club for three years, said: “We’re also concerned because we are always in the water and we have a lot of ski races that take us up that way."
Ray Bush, 64, has been a member of the club since 1996 and a committee member for two years.
He said: “I’m not very happy with it as people won’t want to go into the water again.”
Magnox, who runs the site, has said that discharges to the estuary within safe limits have already been taking place regularly for more than 50 years.
A Magnox spokesman added: “Magnox is sensitive to the local environments in which it operates and is committed to decommissioning Bradwell with the highest regard to safety and the environment.
“Our work programme is fully compliant with regulatory requirements and we will ensure that it remains so as clean-up of the site continues."
An Environment Agency spokesman said:"We take account of impacts on the local environment when setting limits and carry out our own environmental monitoring in the local area to determine levels of radioactivity in the estuary."
