Before entry is permitted to the MRI suite all
unit staff or authorized personnel must have read carefully and
completed an occupational health MRI unit screening form(Contact
occupational health ext. 74810). High magnetic fields may cause
certain medical devices and applications to malfunction, and any
metallic particles in the body to move or become hot, causing injury.
The MRI suite consists of 2 areas:-
The outer controlled area consists of a main
preparation area and computer operation area. This outer controlled
area will not experience magnetic fields greater than the general
safety limit of 5 Gauss. All users will have to complete an occupational
health MRI screening form prior to going into this area. A document
on MRI safety at Cardiff can be obtained from here.
It is recommended that this document is read prior to commencement
of any work.
The inner controlled area can only be accessed
via the outer control area. Access to this inner area will be strictly
for authorised personnel who have received the correct training.
Within this inner area magnetic fields strength exceeds 30 Gauss.
At this level of magnetic force, ferrous metallic objects become
In addition to items on or within a body, no additional unauthorized
equipment from outside the suite (i.e. cages, trolleys, etc) will
be allowed into the MRI suite without prior approval. In particular
no surgical equipment will be allowed into the MRI suite. A range
of MRI compatible surgical tools will be made available for users.
Further screening and safety checks will be carried out for people
entering the inner controlled area such that any metallic objects
(such as keys, hair clips, swipe cards, mobile phones, jewellery,
etc) have been removed. The checklist of objects to be removed before
entering the inner controlled area is here.
To arrange a health and safety appraisal for the MRI
unit contact occupational health on ex. 74810. For any further enquires
on general MRI safety contact Bill Edwards on ex. 75136.
