Linac, Cyberknife and TomoTherapy shielding doors, bunker lead shielding and shielding upgrades along with a full neutron shielding service for higher energy bunkers available from DHA!
DHA have recently installed both swing and sliding automated shielding doors at the Mount Vernon Hospital Cyberknife facility and St Thomas’ Hospital TomoTherapy unit.
Manufactured by DIB in Dijon, France, the doors are of very high quality, meeting all European standards, and can be tailored for any Linac photon energy, with or without an entrance maze. There are sliding-door variations running on lintel mounts or rails if very heavy and swing doors, addressing all possible requirements. These door systems offer great value, are easily serviced, and come with a twenty-year guarantee. They are suitable for any Linac, Tomotherapy or Cyberknife room. They can be finished in stainless steel, wood veneer or a bespoke paint colour matching all possible room designs and styling.
We have also recently installed a 44 tonne sliding door at Diamond Light Source and bespoke heavy doors, running on rail systems below the floor are a speciality product especially for direct entry, maze-less, space saving bunkers! Our 5 conventional swing door systems located at St James Hospital in Leeds have been working extremely reliably since the centre opened and operate in a very busy and demanding clinical environment.
DHA can now supply in combination with these services, extruded “Chevron lead rail” from Calder Industrial Materials for the upgrading of existing bunkers to support conventional Linac, Cyberknife and Tomotherapy systems or for brand new bunker builds. The Chevron lead rail is 10cms high and can be supplied in a variety of thicknesses and lengths while a design, project management and installation service is available to all customers.
DHA and Radiation Technology Limited have teamed up to provide a cost effective and comprehensive shielding design service for both new and existing high energy radiotherapy Linac bunkers.
Alan Sherwin, CEO of Radiation Technology Limited, is a long-established authority on neutron shielding, and has particular expertise in the design of high-energy Linac facilities. Alan pioneered the use of neutron-absorbent room/maze linings in the early 1980’s, and most of the lined Linac mazes in place today were built to, or derived from, his innovative designs. RTL provides detailed practical advice and guidance, based on 3D bunker modelling and Monte-Carlo calculations, accurately predicting the shielding required and it’s optimal location. RTL’s designs now incorporate its own latest cost-efficient shielding products such as n-Modex neutron moderating granules and BoraTex boron-faced paper for capture of thermal neutrons. New simplified methods have greatly reduced installation costs. DHA are providing RTL with sales and marketing support. Installations in Nottingham, Portsmouth and Inverness have recently taken place. Neutron shielding is usually required for open maze bunker entrances with Linac energies in excess of 12MV.
I will be attending this congress and will be free to discuss the above products and services.
I will be on my www.RadPro.eu booth located on the lower exhibition level.
