The method of optimal measurement counting time in Gamma spectrometry for soil samples was studied. Gamma spectrometry was done based on minimum detectable activity using the HPGe- p type with efficiency of 30% and FWHM 1.7keV (for 1.33 MeV 60Co). The samples were IAEA-RG Th-1, IAEA-RGU-1 and IAEA-RGK-1 prepared in bottles. The measurements were done for 12 different counting times from 5 min t...

A measurement station dedicated for quantitative radiological characterisation of naturally occurring radionuclides in a metallurgical company and based on gamma-ray spectrometry was developed. The station is intended for performing quality control of final non-ferrous metal products and for radiological checks of incoming materials. A low-background point-contact HPGe-detector was used and the...

The 12 NaI(Tl)-detector gamma-ray spectrometry system (GSS) “Romashka”[1,2] has recently been equipped with a new computer controlled HVSys 16 channel high-voltage power supply with preselected single channel polarity [3] (Fig.1). In order to do some preliminary checks of the GSS chains’ characteristics, a single channel gamma-spectrometry tract was commissioned. It was consist of a single Roma...

Background: The increasing amount of sewage sludge (SS) and more legislative regulation of its disposal have stimulated the need for developing new technologies including gamma irradiation to recycle SS efficiently. Objective: To evaluate the effects of gamma irradiated and non-irradiated SS (SSGI and SSNI, respectively) on essential oil (EO) content and composition of Ocimum basilicum L. Me...
