Gamma radiation measurements and dose rates in commercially-used natural tiling rocks (granites)
(2003)The gamma radiation in samples of a variety of natural tiling rocks (granites) imported in Cyprus for use in the building industry was measured, employing high-resolution γ-ray spectroscopy. The rock samples were pulverised, ...

Photochemistry of an azido-functionalized cryptand: Controlling the reactivity of an extremely long-lived singlet aryl nitrene by complexation to alkali cations
(2005)Photolysis of the cryptand 1, bearing an intraannular azido substituent, results in a complex photochemistry. Low-temperature photolysis yields the triplet nitrene 32, which has been characterized by EPR spectroscopy. Small ...

Radiometric analysis of potassium, radium and uranium levels in Brazil nuts
(Springer, 2023)The paper describes an alternative approach for the determination of uranium, radium-226 and potassium levels in Brazil nuts. Potassium analysis was performed by a NaI detector using 1-gram of nut’s ashes, radium analysis ...
