Applications

133Xe is used in medical studies for: Diagnostic evaluation in pulmonary

function. Imaging the lung. Assessment of cerebral blood flow. Fetal risk diagnoses.

133I, 133Xem and 133Xe are fission products. Xenon isotopes are of particular interest in reactor operation.

• 133Xe: I from 1992MA05 values not were considered in previous evaluations.

• Recalculated %I using interpolated ICC from 2002BA85.

• Recent E from 2000HE14.

• Recalculated E and %

• New measurements of the half-lives and Iare highly recommended.
