Gyt Radionuclides: A Case Study

Decent Essays

On the Ailinginae atoll, a total of 18 residents (7 under 20 years old) obtained 0.69 Gyt; 157 total (74, under the age of 20) on Utrik were exposed to 0.14 Gyt (Takahashi, 1999). Some residents developed skin lesions from an estimated skin dose of 100 Gyt to 150 Gyt (Sutow, 1965). There was an estimation of 1 Gyt to 1.5 Gyt radioiodine exposure to adults and slightly higher for the children (Sutow, 1965). The majority of the radionuclides absorbed internally by the thyroid were short-lived and ingested from contaminated utensils, water and food (breast milk as well) (Sutow, 1965). Overtime, bone marrow depression improved to almost normal, for all the previously exposed, by the first year (Robbins, Date unknown). There was prompt restoration of skin lesions and an eventual hair regrowth and re-pigmentation (return of skin color) with only lingering hyperpigmentation (skin darkening) plaque (patch) and nevi (flat or raised) in some areas of skin (Robbins, Date unknown). …show more content…

Following the return of the people to Rongelap, there were 39 births to previously radiated parents and 53 births from the unexposed population by the year 1963 (Sutow et al, 1965). The estimated rates of exposure, stated previously, is important for estimating short and long term effects on the exposed populations. Especially the exposed children, because they are at higher risk for future radiation exposure effects, as explained by the Law of Bergonie and Tribondeau. The exposed children need to be monitored because they will most likely require treatment, as they get older due to their sensitive thyroid
