Professional testings
Under tests by RRPPS (Radiation Protection Service within the Imaging & Medical Physics Group of University Hospital Birmingham NHS Trust) using a 37GBq241 Americium source, there were no discernable radiation leakage paths.
The door design included hardwood rebated frame, architraves, door leaves with rebated meeting styles, and vision panel with cloak type chamfered glazing bead.
It is important that the radiation Technical Advisor appointed specifies the lead equivalence required, taking into account the radiation source, its position and frequency of use.
Fire Resistance
The doorset has been tested at Chiltern International Fire in accordance with BS 476 part 22. The result achieved well in excess of FD60 fire resistance. The over run in performance will allow if necessary for an evaluation to increase the door dimensions and glazed area. During the fire tests the doors were assessed with the latch wired open, which means that a latch does not have to be fitted to retain the fire certificate. Any other ironmongery used has to be carefully considered to ensure that it does not compromise the fire performance and the fire certificate.
Ironmongery
Our radiation door should be hung on 4 hinges per leaf using "Loadmaster" Code 7935 from Cooke Bros. Other ironmongery can be incorporated, but cutting away or piercing the protection should be avoided. Kick and push plates can be recessed into the face of the door if required.
Due to the design the lock case is sandwiched between two layers of lead so minimising the effect of the lock case as a breech in allowing radiation leakage.
Glazing
Our doorset was tested with vision apertures incorporating lead glass, lead protection to the beads and aperture prevents radiation leakage.
Smoke and Intumescent Seals
Depending on the safety needs, appropriate fire and smoke seals can be fitted to comply with BS 476 pt 22 and 31.1.
Manual Handling
Under the Manual Handling Regulation 1992, a risk assessment needs to be carried out for the handling of our radiation doors. They are considerably heavier than similar sized standard doors. The doors weigh 78kg/m3 and appropriate handling should be introduced when moving and during installation.
Choosing our radiation resistant doors means you can be sure the safety requirements of your building do not take second best.
