PURPOSE OF THE UNIT STANDARD 
This unit standard requires learners to select the correct instruments for radiation and contaminant measurements. Selected instruments must be appropriate for the type of radiation or contaminant to be measured, and the expected level of radiation or contaminant to be measured.

    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO ORGANISING 
    Organise and manage oneself and one's activities responsibly and effectively when all relevant sources of information are located within specified time frame and Information regarding measurement is accessed according to specified procedures. 

    UNIT STANDARD CCFO COLLECTING 
    Collect, analyse, organise and critically evaluate information regarding measurement, to determine type and level of radiation or contaminant to be measured within specific contexts and to assess the suitability of instruments for specific measurements. 

    UNIT STANDARD CCFO SCIENCE 
    Use science and technology effectively and critically, showing responsibility towards the environment and health of others when expected level of radiation or contaminant determined is relevant for specific contexts, and to assess the suitability of instruments for specific measurements. 

    UNIT STANDARD CCFO DEMONSTRATING 
    Demonstrate an understanding of the world as a set of related systems by recognising that problem-solving contexts do not exist in isolation when the area/environment to be surveyed is described in terms of relevant characteristics that impact on measurement and the type of radiation or contaminant determined is relevant for specific contexts. 

    UNIT STANDARD ASSESSOR CRITERIA 
    Assessors should keep the following principles in mind when designing and conducting assessments against this unit standard:
  • Focus the assessment activities on gathering evidence in terms of the main outcome expressed in the title to ensure assessment is integrated rather than fragmented. Remember we want to declare the person competent in terms of the title. Where assessment at title level is unmanageable, then focus assessment around each specific outcome, or groups of specific outcomes.
  • Make sure evidence is gathered across the entire range, wherever it applies. Assessment activities should be as close to the real performance as possible, and where simulations or role-plays are used, there should be supporting evidence to show the learner is able to perform in the real situation.
  • Do not focus the assessment activities on each assessment criterion. Rather make sure the assessment activities focus on outcomes and are sufficient to enable evidence to be gathered around all the assessment criteria.
  • The assessment criteria provide the specifications against which assessment judgements should be made. In most cases, knowledge can be inferred from the quality of the performances, but in other cases, knowledge and understanding will have to be tested through questioning techniques. Where this is required, there will be assessment criteria to specify the standard required.
  • The task of the assessor is to gather sufficient evidence, of the prescribed type and quality, as specified in this unit standard, that the learner can achieve the outcomes again and again and again. This means assessors will have to judge how many repeat performances are required before they believe the performance is reproducible.
  • All assessments should be conducted in line with the following well documented principles of assessment: appropriateness, fairness, manageability, integration into work or learning, validity, direct, authentic, sufficient, systematic, open and consistent

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
