Unit of competency
Modification History
Release 1. Supersedes and is equivalent to MEM24009B Perform basic radiographic testing.
Application
This unit of competency defines the skills and knowledge required to perform basic radiographic testing procedures and work with ionizing radiation in open and closed sites on fabrication, structures and components across a wide range of industries and industrial applications. It applies to situations where knowledge of metallurgy associated with the level of application in this unit is required.
All testing must be completed with particular attention to personal and WHS regulations. Ionizing radiation equipment materials and chemicals, which are subject to codes and regulations, must be stored, used, and transported in accordance with safe work practices.
This unit should not be selected when unit MEM24010 Perform radiographic testing has already been selected.
Where interpretation of technical drawings is required unit MEM09002 Interpret technical drawing should also be selected.
Where the selection and use of engineering measurement is required unit MEM12023 Perform engineering measurements should also be selected.
Where the selection and use of power tools are required unit MEM18002 Use power tools/hand held operations should also be selected.
No licensing or legislative requirements apply to this unit at the time of publication. Certification against Australian Standards may be achieved where assessment in this unit of competency is carried out in conjunction with an examining authority as described in AS ISO 9712 Non-destructive testing — Qualification and certification of NDT personnel.

Assessment requirements
Modification History
Release 1. Supersedes and is equivalent to MEM24009B Perform basic radiographic testing.
Performance Evidence
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include:
- following work instructions, standard operating procedures (SOPs) and safe work practices
- identifying and interpreting specifications, relative testing and conformance standards for performing basic radiographic testing
- preparing the area for testing and identifying discontinuities including observed changes in material homogeneity and in accordance with procedures
- applying safety practices and controls for minimising radiation exposure including effectively designing exposure and storage areas and calculating shielding thickness in accordance with procedures
- carrying out basic radiographic testing using techniques and equipment appropriate for material/s to be tested, calculating and producing optimum quality radiographs on at least two occasions
- producing films to achieve optimum results and documenting and reporting test results in accordance with procedures and customer service requirements on at least two occasions.
Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.
Knowledge Evidence
Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:
- safe work practices and procedures and use of personal protective equipment (PPE)
- cleaning and preparation processes for test surfaces
- assessment procedures and techniques
- types of discontinuities and their effect on the material
- procedures for carrying out each radiographic test and for specialised radiographic applications
- principal types of X-ray generators and radioisotopes and their effect on radiographic sensitivity
- tools, equipment, techniques and system verification checks
- relevant standards, regulations and codes
- principles of image formation, film and chemical properties and processing techniques
- different types of films and screens, their properties and effects on image quality
- maintenance and storage procedures for test equipment
- common faults and damage
- safety features of radioisotope cameras and X-ray equipment
- production of X-rays and gamma rays and comparison of them on basis of energy and intensity
