Radiation source:
▪ Should be properly selected in term of activity, half-life, radiation type and energy
according to application.
▪ The half-life should be as short as possible and not greater than the useful life of
the system.
▪ Should be of the lowest activity, radiotoxicity and energy.
▪ Should be in solid form and preferably in special form to minimize leakage and
contamination.
▪ Should be designed, manufactured and tested according to recognized standards
and accompanied by certificate as an evidence/proof.
