Registering and decommissioning radiation workspaces聽
Radiation workspaces must have written approval by the Radiation Protection Team before any work with ionising radiation takes place.

Areas where聽work聽with ionising radiation聽is carried out聽are evaluated on the radiation聽risk from the work that will be conducted in that聽area.鈥� Stricter controls are applied for higher-risk work areas.
Radiation Workspaces (designated areas)
Designated Areas are a legal requirement and their purpose is to help manage the radiation risk by identifying and segregating higher risk activities from the lower, and thus controlling the extent of radiation exposure.

Controlled Area
This is the highest category.聽A Controlled Area is an area where either a person聽might receive over three-tenths of the relevant annual dose limit, or 鈥渟pecial procedures鈥� have to be followed which are designed to restrict significant exposure, or to prevent or limit the probability or magnitude of radiation accidents.聽Note - special procedures are deemed to not include routine work with low levels of radionuclides.
Supervised Area
A Supervised Area is an area聽where either a person聽might receive more than one-tenth of the relevant annual dose limit, or the conditions of the area need to be kept under review to determine whether it could become a Controlled Area.
Registered Area
Radiation workspaces that do not require designation as either Supervised or Controlled are called Registered Areas at 果冻影院.
Types of radiation work areas

- X-rays or other radiation generators
Registering new or refurbished work areas or radioactive waste stores
Early notification of projects that involve聽the creation or refurbishment of an area to be used for work with ionising radiation or storing聽radioactive waste will ensure that projects are not delayed or additional expenses incurred whilst waiting for approval.
The Radiation Protection team will provide the correct advice including:
- Layout (e.g. location of workbenches, sinks, clean areas)
- Surface finishes (e.g. walls, floors, laboratory furniture)
- Pipework (including sinks, drainage and taps)
- Furniture (including workbenches, fume cupboards and laboratory storage)
- Security
- Shielding
- Signage
Email the Radiation Protection Team to register聽new or refurbished work areas or waste stores.
Decommissioning of radiation work areas or radioactive waste stores
Radiation areas, including radioactive waste stores, must be formally decommissioned:聽
- When work with radioactive materials in the area has ceased
- Prior to any work not involving ionising radiation in the area
- Prior to refurbishment聽
- Prior to demolition聽
Departments must follow the 聽(果冻影院 login required).
