Required knowledge

Required knowledge includes

health safety and emergency procedures relevant to radioactive devices

factors affecting radiation intensity

principles of external radiation protection and practical methods of minimising radiation exposure

methods of measuring and detecting ionising radiation

nature of radiation different types of radiation their characteristics sources and shielding methods

physiological effects of ionising radiation

state or territory licensing requirements

national codes of practice

general guidelines for safe handling of radiation sources

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors should ensure that candidates can

perform operations in accordance with standards codes procedures and enterprise requirements

safely handle store and transport instruments keeping other people clear of radiation sources

perform and document radiation surveys

recognise interpret and report problems to appropriate personnel promptly

Context of and specific resources for assessment

This unit of competency is to be assessed in the workplace or simulated workplace environment

This unit of competency may be assessed with

MSLA Process and interpret data

MSL924001A Process and interpret data

MSLA Participate in laboratoryfield workplace safety

MSL943002A Participate in laboratory/field workplace safety

MALA Perform mechanical tests

MAL974010A Perform mechanical tests.

Resources may include

appropriate tools instruments equipment and materials

enterprise procedures test methods equipment and manuals

Method of assessment

The following assessment methods are suggested

analysis of work completed by the candidate over a period of time to ensure accuracy consistency and timeliness

observation of candidate using the instruments in a range of work contexts

review of enterprise documentation completed by the candidate

feedback from peers and supervisors

use of suitable simulation andor a range of case studiesscenarios

In all cases practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly

Where applicable reasonable adjustment must be made to work environments and training situations to accommodate ethnicity age gender demographics and disability

Access must be provided to appropriate learning andor assessment support when required

The language literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work like environment

This competency in practice

Industry representatives have provided the case study below to illustrate the practical application of this unit of competency and show its relevance in a workplace setting

Construction materials testing

Soil moisture density gauges are used extensively for measuring the density of soils cement treated roadbase roller compacted concrete and asphalt They provide a nondestructive means of monitoring compaction operations during construction so that additional rolling can be provided before the material sets or is covered with another layer National and stateterritory codes of practice regulate the use of equipment that emits ionising radiation States and territories also have licensing and registration requirements for people involved in owning storing transporting or using such equipment

Soil moisture density gauges are used on construction sites so they are transported to the test site in motor vehicles They must be protected from damage and stored safely and securely while not in use The operator must ensure that bystanders are kept clear to minimise radiation exposure Owners of gauges are required to have documented procedures and ensure that operators are adequately trained To ensure the safety and integrity of the gauge radiation surveys are required at regular intervals A handheld radiation meter is used and the results recorded
