Rayshielde Radiation Shielded Fire Door


Any exposure to ionising radiation carries a risk. Everyday bodily functions of the human body are altered when exposed to radiation rays, causing harm to almost every part of our body. This can occur in hospital areas like the radio therapy and x-ray rooms which emit radiation rays. In order to protect hospital employees and patients against unwanted exposure to unnecessary harmful rays, the Rayshielde™ Radiation Shielded, lead-lined doors provide an optimum solution. Lead sheet of various thicknesses can be incorporated to provide the required “lead equivalence”. In order to provide maximum protection, the internal lead sheeting covers the full height and width of the door. Lead glass vision panels can be provided if communication or inspection is required.
Normal method of construction of a radiation shielded door is to incorporate two layers of lead either side of the central core. The external finish sheets are then laminated to the lead layers to complete the door construction.
This method of construction offers many benefits such as:
- The double lead layers provide a balanced construction.
- Locks, hinge recesses and associated fixings are protected by the layers of lead.
- Fire rated options available.
- Single, pairs and unequal pairs are available.
- Vision panels can be incorporated.
