Abstract

The tritium bioassay programme at the Savannah River Plant is geared for rapid urinalysis of large numbers of samples. More than 300 000. urine samples have been analysed in the past ten years. A liquid scintillation counting procedure currently used for analysis of urine samples is described. Untreated samples containing as little as 1{mu}c of tritium per litre can be assayed in one minute. The detection limit for distilled urine is 5 x 10{sup -4} {mu}c of tritium per litre. Automation of equipment, optimum scintillation mixture and sample volumes, selection of reagents and counting containers, and elimination of interfering radionuclides are discussed: Empirical studies of biological half-life are summarized. In 310, cases where the initial-tritium conr centrations in urine ranged from 20 to 118 {mu}c/l the average biological half-life was 9.5 d. The half-life varied inversely fwith ambient temperature and'age of employees.

Il suffit d'une minute pour doser le tritium dans des echantillons d'urine non traitee qui, en,contiennent une quantite pouvant n'atteindre que 1 {mu}c/l. La limite de detection pour l'urine distillee est de 5 * 10{sup -4} {mu}c/l. L'auteur traite de ['automation des appareils, des volumes optimums pour le scintillateur et l'echantillon, du choix des reactifs et des recipients pour le comptage, et de l'elimination des interferences dues a d'autres radionucleides. Le memoire contient egalement un resume d'etudes empiriques sur la periode biologique. Dans 3-10 cas ou'la concentration initiale de l'urine en tritium etait de 20 a 118 {mu}c/l, la periode biologique moyenne etait de' 9,5 j. La periode variait en raison inverse dela temperature ambiante et de l'age des sujets. (author) [Spanish] En la planta del rio Savannah se ha organizado un;programa de determinacion del tritio basado en ei analisis rapido de gran cantidad de muestras de orina. En los diez ultimos anos se han analizado mas del 300 000 del estas muestras. Se describe un metodo de recuento, basado en un centelleador liquido, que se utiliza corrientemente para el analisis de las muestras de orina. El metodo permite determinar en 1 min muestras sin tratar que solo contienen 1 {mu}c de tritio por litro. El limite de deteccion, en el caso de la orina destilada, es de 5 * 10{sup -4} {mu}c de tritio por litro. Se examina la automatizacion del equipo, la mezcla de centelleo y los volumenes de muestras optimos, la seleccion de reactivos y de recipientes de recuento, y la eliminacion de radionuclidos susceptibles de interferir. Se resumen los estudios empiricos realizados sobre el periodo biologico. En 310 casos en que la concentracion inicial de tritio en la orina estuvo comprendida entre 20 y 118 {mu}c/l, el periodo biologico medio fue de 9,5 d. El periodo biologico vario en relacion inversa a la temperatura ambiente y a la edad de los individuos.
