Isto resultava in le dis- veloppamento tardive de insufficientia thyroide e/o de nodulos thyroide in 80 pro cento de ille juveniles. Al tempore presente, le effectos thyroide constitue le sol importante patente problema medical in le exponite population. Le detection de damnification thyroide esseva impedite per le lente modo de su declaration e per le inexpectatemente alte concentrationes sanguinee de iodoproteina in le population marshallese in general. I] es probabile que le elevate incidentia de anormalitates thyroide in le juveniles es 'e effecto de duo factores: (1) Un major intensitate del irradiation in consequentia del minor dimensiones del thy- roide e (2) un plus forte susceptibilitate de un organo in crescentia pro manifestar alterationes causate per interferentias chromosomal. Le spectro de possibilitates de exposition del glandulas thyroide a irradiation es extense in omne population. Illo include precipitation stratospheric ab explosiones atomic, tests clinic con isotopos radioactive de iodo, e alte intensitates de irradiation intentionalmente producite in le therapia de morbo thyroide. Le experientia marshallese va adjutar in definir le region de intensitates irradiatori associate con le occurrentia de significative damnos thyroide. REFERENCES 1. CRONKITE, E. P., Bonn, V.
