Abstract
Abstract A radiation source for Mossbauer investigations of tellurium compounds manufactured on the basis of 5MgO.Te 124 O 3 made by method of preparing this radiation source comprises irradiating 5MgO.Te 124 O 3 in a reactor by means of thermal neutrons, followed by annealing at a temperature ranging from 600° to 1,100° C for a period of from 5 to 10 hours.
