Abstract

A description is given of an accident involving extremely uneven irradiation (ranging from 50 rads to 1.7 Mrads), in which a worker carried a {sup 137}Cs source belonging to an industrial gamma radiography unit in his trouser pockets for a total period of 18 hours on 3 and 4 May 1968. Low irradiation of the haematopoietic and gastrointestinal organs inhibited the occurrence of the acute syndrome. The front of the thighs, the inguinoscrotal region, and to a lesser extent the hands, were the areas most affected by lesions. The radiation doses delivered to the affected areas were estimated from biological radiation dosimetry parameters (the extent and chronological order of some of the lesions) and from experimental data on the dose as a function of distance and depth of the tissues, obtained by reconstructing the accident with a phantom and a set of thermoluminescent dosimeters. The paper describes the appearance a few days later of wet radiation dermatitis covering areas which gradually grew until they reached approximately the limit represented by the 1000 rads isodose line. Progression of the radiation dermatitis was complete towards the end of May. At the beginning of June dry epidermal desquamation extending approximately as far as  More>>

The paper describes the appearance a few days later of wet radiation dermatitis covering areas which gradually grew until they reached approximately the limit represented by the 1000 rads isodose line. Progression of the radiation dermatitis was complete towards the end of May. At the beginning of June dry epidermal desquamation extending approximately as far as the 500 rads line was observed. With the passage of time there occurred muscular atrophy of both legs and extensive oedema of the inguinoscrotal area. The appearance of extensive femoral haemorrhages in November 1968 and January 1969 made it necessary to amputate first the lower left limb, and then the right. The rate of chromosomal aberrations in the peripheral blood confirms the low doses absorbed by the blood system (about 50 rads). A summary of results of the analyses made is given, together with comments on the prognosis of the patient's development, based on the distribution of the radiation dose received. (author) [Spanish] Se describe un accidente de irradiacion fuertemente inhomogenea (del orden de 50 rad a 1,7 Mrad) en el cual un obrero llevo en los bolsillos de su pantalon una fuente de {sup 137}Cs, perteneciente a un equipo de gammagrafia industrial, durante un lapso fraccionado de unas 18 h, los dfas 3 y 4 de mayo de 1968. La baja irradiacion de los organos hematopoyeticos y gastrointestinal impidio la aparicion de sindrome agudo. Las caras anteriores de los muslos, la region inguinoescrotal y en menor grado las manos, fueron las zonas mas lesionadas. Se han estimado las dosis de radiacion recibidas en las zonas afectadas a partir de parametros de radiodosimetrfa biologica.( extension y secuencia temporal de algunas lesiones) y datos experimentales sobre la variacion de las dosis con la distancia y la profundidad de los tejidos, obtenidos mediante la reconstruccion del accidente con un 'fantomas' y un conjunto de dosimetros termo- luminescentes. Se describe la aparicion a los pocos dfas de zonas de radiodermitis humeda que se extendieron paulatinamente hasta aproximadamente el limite representado por la linea de isodosis de 1000 rad. La progresion de la radiodermitis se completo hacia fines del mes de mayo. A principios de junio se observo la aparicion de una descamacion epidermica seca hasta aproximadamente la linea de 500 rad. Con el transcurso del tiempo se observo la atrofia muscular de ambas piernas y un edema importante de la zona inguinoescrotal. La aparicion de hemorragias femorales importantes en noviembre de 1968 y enero de 1969 motivo la amputacion primero del miembro inferior izquierdo, luego del derecho. El indice de frecuencia de aberraciones cromosomicas en sangre periferica confirma las bajas dosis recibidas por el compartimiento sanguineo (alrededor de 50 rad). Se presenta un resumen de los resultados de los analisis realizados y se comenta el pronostico de la evolucion del paciente en base a la distribucion de la dosis de radiacion recibida. (author)}
