The nuclear level structure of ¹⁰¹Ru has been investigated
through the decay of 14.0 minute ¹⁰¹Tc produced by thermal neutron
irradiation of molybdenum targets. Gamma-ray energies and relative
intensities have been measured with the high resolution Ge(Li) spectrometers.
Based on the energy sum and the intensity balancing, a
consistent level...
There is an increasing world inventory of radiotechnetium (mainly
⁹⁹Tc) and it is inevitable that some of this will be released to the
environment. However, little is known about the environmental behavior
of this element.
This work examined technetium's behavior in two representative
freshwater species, the pearl mussel (Margaritifera margaritifera)...
The patterns of uptake, retention, and tissue distribution of
⁹⁵mTc in two freshwater species, the crayfish Pacifastacus
leniusculus and the snail Juga silicula have been investigated. The
animals were chronically exposed in water to which sodium
pertechnetate had been added. Final whole-body concentration ratios
(CR) obtained were 1.6 and 41...
