Regulations require a license for the sale of radioactive substances in Switzerland. Swiss customers are kindly requested when ordering, to include their license number, issued by the Swiss Public Health Authorities.
Effects of separate and combined action of 232Th and Cd on Allium cepa root tip cells were investigated. It has been shown that cytogenetic effects of 232Th results mainly from its ability to induce genome damages. Cadmium in the examined

A method for determining the specific alpha activity of thick sources using a large area ZnS(Ag) scintillation detector is presented. In this method a quadratic relationship between the detector response and window thickness is assumed. This method provides a quick

Electron paramagnetic resonance (EPR) studies were conducted on gamma irradiated polycrystalline sample of thorium nitrate pentahydrate, Th(NO(3))(4)·5H(2)O, in the temperature range of 100-300 K. The most prominent species with triplet hyperfine structure in the EPR spectrum was identified as NO(2).
We studied histomorphology of the CBA line mice liver after 30 and 90 days of the low dose gamma-radiation influence combined with incorporated Th(NO3)4 in doses 0.03; 0.1; 0.3 grams per kilogram of the living mouse weight. Morphophysiological and morphometric

Electrospray ionisation mass spectrometry (ESI-MS) is a useful tool for exploring the speciation of solution-phase metal complexes; however, the quantification of ternary systems is challenging due to the differences in the electrospray response of different species. Here, the Th-Mn-EDTA system
