Tritium radioactivity estimation in cement mortar by heat-extraction and liquid scintillation counting

open access: yesNuclear Engineering and Technology, 2021
Tritium extraction from radioactively contaminated cement mortar samples was performed using heating and liquid scintillation counting methods. Tritiated water molecules (HTO) can be present in contaminated water along with water molecules (H2O).

Oral paltusotine, a nonpeptide selective somatostatin receptor 2 agonist: Mass balance, absolute bioavailability and metabolism in healthy participants

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Aims Paltusotine is a novel, nonpeptide, selective somatostatin receptor 2 agonist in development for the treatment of acromegaly and carcinoid syndrome. This study investigated the mass balance, routes of excretion, absolute bioavailability and metabolite profile of orally administered paltusotine.

On the interference of 210Pb in the determination of 90Sr using a strontium specific resin [PDF]

open access: yesNuclear Technology and Radiation Protection, 2013
We investigated the interference of radiolead in the isolation of radiostrontium using a strontium-specific resin by means of 85Sr and 212Pb radiotracers. The resin was found to be almost equally specific for lead ions as well.

Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.
