The course provides an opportunity to refresh radiation protection and safety knowledge and the requirements of the Industrial Radiography Code*, the Transport Code* and the Security Code*. Over time previously learned information can fade, poor habits can creep in, and some skills can diminish. The Planned Exposure Code* requires the Responsible Person to provide refresher training to minimise this (and the operator to participate). IAEA SSG-11 requires radiation safety and protection refresher training to be typically given at intervals of less than two years but not exceeding five years. Under ISO 9712 there is also a requirement for continuing professional development through the structured credit system used in renewal. Non-conformances may also have been identified through an audit for an accredited NDT laboratory (such as NATA). This training course provides an opportunity to help with satisfying these requirements.
