Mohawks install hospital radiation bunkers


MOHAWK STEELWORKERS are installing Europe's first prefabricated composite radiation bunkers at a Hertfordshire hospital.

It will take only two weeks for the five new radiotherapy treatment rooms to be assembled from US-manufactured modules at the Mount Vernon Cancer Centre, near Rickmansworth.

Supplier RAD's European operations president David Naylor said the Mohawks were employed because the system required precise assembly to ensure no radiation leaks.

'Nobody understands steel construction better than these guys, ' Naylor added.

Each bunker will contain a linear accelerator. This equipment is normally shielded by up to 2m of reinforced insitu concrete.

But the patented RAD Technology systems now being installed are based on the use of hollow steel box sections filled on site with a specially blended dry aggregate.

Overall wall thickness is similar to traditional concrete.

Client East & North Hertfordshire NHS Trust said the innovation will allow completion of the £20M redevelopment of cancer treatment facilities 17 months early. This will allow 4,500 extra cancer patients to be treated.
