Radiological hazard assessment of natural gross radioactivity in some cosmetic products

Many kinds of cosmetic products were analyzed to determine gross radioactivity. In this study, gross alpha/beta radioactivity concentrations in 51 cosmetic samples were determined. The examined cosmetic products consist of blusher, eye shadow, lipstick, nail polish, shampoo, hand cream, cellulite cream, baby powder, soap, and toothpaste. The gross alpha–beta activity concentrations were measured with a nuclear spectroscopic system which contains gas-flow proportional counters. The highest gross alpha/beta activity concentrations were found in eye shadow samples of 1.621Bq g^?1 for alpha and 6.471Bq g^?1 for beta. The total effective doses due to gross radioactivity for skin were calculated. Although the effective dose of eye shadow samples had the highest value, the effective doses due to gross radioactivity concentrations in this study were found to be lower than the radiological limits given by the authorities.

Feeding,tube-building and particle-size selection in the terebellid polychaete Eupolymnia nebulosa

The present study was aimed at obtaining new information on the feeding biology of the terebellid polychaete Eupolymnia nebulosa (Montagu). Feeding, tube-building, particle-size selection, and tentacular morphology are described. Experiments were carried out during the fall of 1984 on specimens collected in the vicinity of Banyuls-surmer, France. Feeding activity takes place almost entirely in darkness, and E. nebulosa shows a marked preference for smaller particles when feeding and selects larger ones for tube-building. The control of its activity pattern by light intensity may result in seasonal modification of its energy balance. The mechanisms controlling particle-size selection in this species are discussed.
