The monetary value of the person-Sievert: a practical approach in case of occupational exposures.

This paper gives some practical advice on the determination of the value of the person-Sievert, this figure being of primary importance when cost-benefit analysis is used to optimize (ALARA-principle) routine occupational exposures of professionals to external radiation. After a brief introduction on the use of cost-benefit analysis in a radioprotection context, more attention will be paid to the theoretical guidelines that exist on the monetary value of the person-Sievert. By combining these insights with the practical problems that occur in daily task preparations and evaluations, a more workable proposal for the determination of the value of the person-Sievert will be presented.

[Urinary excretion of 17-ketosteroids studied by gas chromatography in the healthy adult: distribution of values].

The level of different urinary 17-ketosteroids were assayed using a method requiring an enzymatic hydrolysis and a solvolysis, a separation by gas-chromatography on OV 225 (cyanopropylsilicone) and a detection by flame ionisation. The method has been discuted. Statistical study of the results obtained in 89 healthy and ambulatory subjects (divided in 4 groups according to sex and age) has shown a log-normal distribution of urinary excretions.
