The exposure matrix was developed to account for job, plant, and era dependent differences in TCDD [2, 3, 7, 8-tetrachlorodibenzo-p-dioxin] exposure. The TCDD exposure estimates are based on(1) the concentration of TCDD in micrograms per gram present in process materials;(2) the duration of exposure to TCDD contamination, expressed as a fraction of a work day; and(3) a qualitative contact factor(0. 05-1. 5) to account for the extent of worker contact with the TCDD contaminated material. These three factors are multiplied together to yield a daily TCDD exposure score. The sum of the daily exposure scores constituted an individual' s cumulative exposure score. Daily TCDD exposure scores range from 0. 001 to 1250. Cumulative TCDD exposure scores are distributed from 0. 002 to 1, 651, 611 exposure score days. The TCDD cumulative exposure score, which incorporates both duration and level of exposure, provides a means for ranking workers for evaluating the relationship between TCDD exposure and mortality in a retrospective cohort study analysis. 2, record 3, English, - exposure%20score

The following surrogate measures of dose, for each substance, were used to summarize "likely"’ exposure histories for each study subject: duration of employment in occupation/industry combinations considered exposed, a cumulative exposure score, and "average" intensity of exposure. Odds ratios were calculated for exposure intensity categories to refrain from using weights. 4, record 3, English, - exposure%20score

On détermine le score d'exposition en croisant durée et intensité d'exposition. Ce score est composé de cinq niveaux. Ces scores définissent une échelle d'exposition et non un niveau de risque, celui-ci dépendant du produit chimique concerné. [Tableau]. Score d'exposition en fonction de l'intensité et de la durée (en heures) de l'exposition : [À une intensité très faible correspond un score d'exposition de niveau] 1 pour une durée de moins de 2 heures à dix heures, de [niveau] 2 pour 10 à 20 heures, et de [niveau] 3 pour 20 heures et plus; pour une intensité faible correspondent des scores de 1 pour moins de 2 heures, de 2 pour 2 à 10 heures, de 3 pour 10 à 20 heures et de 4 pour 20 heures et plus; pour une intensité forte correspondent des scores allant de 2 à 5; pour une intensité très forte correspondent des scores de 3 à 5. [...] L'intensité des expositions aux produits chimiques est très faible pour 40 % des situations. Elle se situe aux alentours de 50 % de la VLE [valeur limite d'exposition] pour 47 % des situations, est très forte (égale ou supérieure à la VLE) dans 1,5 % des cas et est inconnue dans les autres cas (11 %). Le score d'exposition est de niveau 1 pour 47 % des situations d'exposition, de niveau 2,3 et 4 dans 36 % des cas et de niveau 5 dans 4,5 % des cas. 2, record 3, French, - indice%20d%27exposition
