Application

This unit of competency defines the skills and knowledge required to work safely with ionizing radiation when performing radiographic testing on fabrications, structures and components in a range of open or closed industrial applications across a wide range of industries.

The work can relate to scheduled and unscheduled maintenance activities, using general tools, specific radiographic testing equipment as specified in maintenance documentation, testing procedures or operator instructions.

All testing must be completed with particular attention to personal and work health and safety (WHS) regulations. Certification against Australian Standards can 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 non-destructive testing (NDT) personnel.

Materials and chemicals that are subject to codes and regulations such as chemicals, explosives, solvents, dangerous materials, acids and noxious waste products must be subject to safe work habits and must be stored and used in accordance with safe work practices.

This unit is a prerequisite to undertaking any other radiographic units of competency.

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.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

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 charts, specifications, relevant organisational policy and procedures and other applicable reference documents in the workplace when working safely with ionizing radiation

employing appropriate ionizing radiation protective measures and personal protective equipment (PPE) relevant to the industrial application on at least two occasions

determining minimum exposure rates and distances from calculations and charts

undertaking numerical operations and calculations associated with determining minimum exposure rates and distances

selecting and using appropriate tools and equipment necessary to monitor radiation on at least two occasions

documenting all safety breaches and recording and reporting in accordance with SOPs

demonstrating the ability to assess risks and handle emergencies.

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 PPE

International System of Units (SI) of radiation in accordance with the National Health and Medical Research Council (NHMRC) and statutory requirements

production of X-rays and gamma rays in relation to radiographic testing activities

principal radioactive sources used in industrial radiography

attenuation factors

known biological effects of radiation

general principles of gas ionization, photographic effect and luminescence

use of film, film badges, ionization chamber devices, quartz fibre and fluorescent

electronic device accuracy limits including energy and range

different SI units of radiation, including becquerel, sievert and gray

exposure limits for personnel as laid down by the radiation authorities in Australia

exposure reduction factors including:

time

distance

shielding

procedures for establishing safe working barriers

relevant techniques and checks

emergency procedures

safety procedures for:

types of X-ray equipment

types of isotope cameras

shielding materials

design and requirements for exposure areas

requirements for storage of radioisotopes

emergency situations, causes and appropriate responses

storage requirements of equipment and materials

legal requirements including:

federal and state/territory regulations and codes of practice

International Commission on Radiological Protection (ICRP) recommended limits for various persons and various parts of the body for short-term, long-term and accumulated exposure

background radiation

duties of Radiation Safety Officer (RSO)

requirements for transport

International Air Transport Association (IATA) regulations

obligations of the licensee.

Assessment Conditions

Assessors must:

have vocational competency in working safely with ionizing radiation at least to the level being assessed, with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires.

Where possible, assessment must occur in operational workplace situations. Where this is not possible or where personal safety and environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must 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.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
