摘要:

A simple and rapid method for the determination of131Cs and137Cs in urine has been worked out. The method is based on the separation of radiocaesium from urine by sorption on a freshly prepared precipitate of Cu(II) hexacyanoferrate, on the separation of the precipitate, and on the gamma-spectrometric measurement of the precipitate activity.

摘要:

In the meteorites trace elements have been determined by instrumental and radiochemical N.A.A. and the cosmogenic radioactivity of22Na,26Al,48V, and54Mn are measured by low-level gamma spectrometry in the two meteorites Hohenlangenbeck and Trebbin fallen November 1985 and March 1988 onto the territory of the GDR. The contents of Rb and Cs in the meteorite Hohenlangenbeck are relatively high indicating a low condensation temperature. Becuase of the small activity ratio of22Na/26Al a lower particle flux in its orbit during the last five years is assumed.
