  1. Source Leak Testing ACADs (08-006) Covered Keywords Source testing requirements, exemptions from testing. Description Supporting Material

  2. Source Leak Testing • Periodic leakage testing : • source containing licensed material (other than tritium) with a half-life greater than 30 days • Solid, liquids • The test shall be capable of detecting 0.005 uCi. • Sources are exempt from testing if • they contain <10 uCi of an alpha emitting material or • <100 uCi of a beta or gamma emitting radionuclide.

  3. Source Leak Testing • Stored and not used sources must be tested once every 10 year • Exception: alpha sources • Alpha Sources must be tested every quarter • Stored source • Not used for six month • Must be removed from its functional position and secured • Tested before returned to service

  4. Source Leak Testing • sealed beta or gamma sources • leak tested every six months • sealed alpha sources must be leak tested every three months. • Principal investigators must have approvals and posses and use sealed rad sources • Users must have training • Sources must be labeled • Security must be in place

  5. Source Leak Testing Exemptions from testing requirements (NRC: 10 CFR 39.35). • Hydrogen-3 (tritium) sources; • Sources containing licensed material with a half-life of 30 days or less; • Sealed sources containing licensed material in gaseous form; • Sources of beta- or gamma-emitting radioactive material with an activity of 3.7 MBq [100 microcuries] or less; and • Sources of alpha- or neutron-emitting radioactive material with an activity of 0.37 MBq [10 microcuries] or less.
