X-ray Analyzers

Tube shutter:

▪ Should be available as part of the tube housing to cut out the radiation beam when the

device is not in use.

▪ Should be interlocked with the tube housing so that their removal will de-energise the X-ray

tube.

▪ Should be designed and constructed that the scattered and leakage radiation dose in one
hour on the surface of the housing for any permissible operation should not exceed those

specified by the manufacturer and/or standards recognised by the AELB.

▪ The shutter should be fitted with a positive closing device.
