This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This Unit Standard requires learners to be able to determine the long-lived alpha activities on a dust-laden filter with an alpha counter. Learners credited with this Unit Standard are capable of:
  • Explaining the specified requirements pertaining to determining long-lived alpha activity.
  • Preparing to determine.
  • Determining long-lived alpha activity.
  • Performing post-determination activities. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    The Unit Standard outcomes and credits are based on the assumption that learners attempting this Unit Standard can already read, write and communicate at NQF Level 4 or equivalent.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    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.
