I?ve recently been to a Cancer Centre where they have a Linac bunker.  But, unlike the normal maze style linac areas I?ve been used to seeing in the past, which are all nicely compartmented away, this one is an open plan style with two huge [what appear to be concrete or steel] doors [approximately 2ft thick] which are operated with electronic power mechanisms. The doors cannot be opened by human hand!

I?m no doctor?but assume these doors are specifically designed for radiation reasons, rather than fire.

The linac in question is not directly along a means of escape. So, if the linac catches fire, occupants can turn away and head towards an alternate escape exit.  It?s in more of a circulation area I?d say.

Should it be compartmented away?

Not seen one of these before in my limited experience of health care premises so just wondered what the experts think!?  Sounds silly, but does it need extra smoke controls as whilst the doors will clearly hold the flames back, I?ve no idea if they?d hold back smoke/toxic fumes, etc.

Any guidance or pointing in right direction is always appreciated.

Do they have cold smoke seals? What size are the door stops?

Presumably such a room would have to be vented - are there dampers in the ventilation system?

Such a door may contain a thick panel of polyethylene.

Would there be any risk to fire fighters should such a room be 'exposed' as a result of a fire?

What sort of power requirements does this equipment have?
