Abstract

The use of plastic scintillation microspheres (PSm) is an innovative technique for measuring the radioactivity of beta-emitting radionuclides. PSm can be produced via different methods; none of which has been assayed at the industrial scale. In the present paper, we evaluate the production of PSm by spray-drying on an industrial scale. Our results indicate that fluorescent solutes were indeed encapsulated within polystyrene producing spherical particles of 10 μm in diameter. Detection efficiencies for the measurement of ³H and ¹⁴C were 3–5 % and 60–75 %, respectively. These efficiencies are comparable to those of PSm produced via other methods.
