Application

This unit of competency defines the skills and knowledge required to perform basic radiographic testing procedures and work safely with ionizing radiation in open and closed sites on metal fabrication and welding trade related industrial applications including fabrications structures and components across a wide range of industries and industrial applications.

The unit covers complying with personal and WHS regulations relating to ionizing radiation equipment materials and chemicals including their storage, use and transportation.

This unit should not be selected when unit MEM24030 Undertake radiographic tests 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.

What You'll Learn

Assessment Requirements

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

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 used in basic radiographic testing 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

absorption of ionizing radiation by matter and the biological effects

gamma ray sources

shielding thickness, exposure techniques and calculations

reciprocity law

preparation and use of exposure charts and radiographic equivalence charts

equipment types and set-up procedures

common types of materials associated with basic radiographic testing and their industrial applications

methods and/or procedures for reporting test results

implications of test results for the particular material and/or application.

Assessment Conditions

Assessors must:

have vocational competency in performing basic radiographic testing at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the current vocational education and training legislation, frameworks and/or standards.

Where possible, assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions that cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.

Conditions for assessment must include access to all tools, equipment, materials and documentation required including relevant workplace procedures, product and manufacturing specifications.
