The increasing use of brachytherapy sources has highlighted the need to confirm the traceability to national standards of air kerma rate measurements made by suppliers and to provide a simple means for the user to check the activity of such sources.

Radiation Protection Dosimetry.
Proposed new protection level X ray qualities using high voltage values between 10 kV and 30 kV have been established and investigated. Measurements are reported of X ray mean energy and spectral resolution, half value layers and air kerma rates

The Mossbauer absorption spectra of FeV 2 O 4 and Fe 2 VO 4 have been obtained. The spectrum of FeV 2 O 4 , which corresponds to that of ferrous iron in tetrahedral coordination, is a single line at 0.91±0.06 mm⧸sec with respect to a stainless-ste

The Mossbauer absorption spectra of α-, β-, γ-, and δ-FeOOH have been examined at room temperature and at 77°K. The isomer shift for the four forms has been shown to be in the range characteristics of the Fe3+ ion. The spectra of β- and γ-FeOO
