SUMARIO Pautas para Justipreciar las Exposiciones a las Raciaciones Gamma Procedentes del Desprendimiento Consecutivo a las Deionacicnes Nucleares ‘Rep4sase aqui el problema de la radiaci6n gamma externa emitida después de depositarse en la tierra el material lanzado. * Las exposiciones a la radizcién procedente de un cainpo de desprendiinientodissepan de la mayor parte de los experimentos de Jaboratorio con respecto a la geoiiciria y al espectro de energia, lo cual hay auc tomar en cuenta al valuar los efectos biolégicos. Adernas del factor de decadencia radiolégica, los efectos se ven afectados porfa exposicién al aire, el resruardo (como por edificios y terreno) y el tiempo de la dosis. Utilizando estos iactores, se ofrece un diagrania idealizado de desprendimicnto para una exptosién superficial de much rendimiento, indicando zonas de diverses grados de contaminacién. Las medidas protectoras corresponden a cuatro tipos distintos: (a) resguardo, (b) evacuacidn, (c) transcurso de tiempo y (d) descontaminacion, ee ee | Nu . - - . oe ! : ‘ weer '*. ‘Clee a: sa? dabatowt eee ore + tw weteaumwe " & Effects of Atomic Weapons.
