Radiotherapy Shielded Doors

PSF, PSF/I, PSH and PSH2

Sliding and hinged shielded doors are installed into Radiotherapy bunkers for treatment units (LINAC, Cobalt Units,....). Tema Sinergie has an experience of over 20 years in designing, manufacturing and installingshielded doors and can offer optimal solutions in terms of: continuity in door-bunker shielding easy and silent running and possibility of manual opening in case of emergency wide supply of safety devices (sensitive safety edges, photocells...) easy maintenance Sliding doors are available in floor-built version (Mod. PSF/I) or not (Mod. PSF). Trenches in which the doors slides are automatically closed by a stainless steel track. Hinged version is available with either one (Mod. PSH) or two hatches (Mod.PSH2). Sliding and hinged doors shielding is composed by lead, paraffin (or borate polyethylene) and cadmium to the required thickness.
