Notes

 

  1. This practice of "Use of XRF or XRD equipment" also includes vacuum switching chamber device (stray radiation emitter)
  2. "Installation/servicing of radiological equipment" only applies to irradiating apparatus, not to sources.
  3. The practice of “supply and distribution of radioactive sources” includes all related ancillary activities such as collection, temporary storage, importation, exportation, shipment to or from the State (for EU countries), transport/carriage, installation and servicing, logistics, etc. This may apply to supply of new sources and/or the collection of disused sources.
  4. Practices involving the use of radioactive sources on-site are generally considered to include necessary carriage of sources to and from the site. In such circumstances, the activity of “transport” should be included under the source inventory but it is not necessary to include carriage as a separate practice.
  5. The practice of “carriage of radioactive sources” includes temporary storage of sources while in transit.
  6. For the practice of 'dental radiography using a handheld intra / oral unit' the following conditions apply:
    • The Licensee shall, for maximum operator protection, ensure that the unit is only operated with an appropriate backscatter shield positioned at the outer end of the collimator cone.
    • The Licensee shall ensure that when selecting and using Positioning Indicating Devices (PIDs), preference is given to models that allow the backscatter shield to remain at the outer end of the collimator cone.
    • If the unit has inherent safety/security features, then, when not in use or idle during the day, the Licensee shall ensure that these features are activated.
    • The Licensee shall ensure that the users of the unit are fully trained in the operation of the unit and that records of such training are maintained and readily available for inspection.
    • The Licensee shall ensure that the unit is only operated with an appropriate collimator cone length such that the skin-focus distance is a minimum of 20 cm for kVp greater than or equal to 60 or 18cm for kVp less than 60.
