FAMILIES have raised health concerns if an electricity sub-station near their homes is extended.

King James' School, in Knaresborough, wants to enlarge the sub-station, in King James Road, following the completion of a major extensions, including a new hall.

Residents' fears of possible radiation were addressed in a report by planning officers, which said advice on sub-stations from the National Radiological Protection Board stated no "material harm" was likely to arise.

The school's neighbours were also concerned about potential loss of light.

However, North Yorkshire County Council planning committee is being recommended to approve the plan when they meet next Tuesday.

County environmental chief Mike Moore said an extension of the sub-station was necessary to upgrade the circuit supplying the school.

He said he could see no objection to the scheme on planning grounds.
