  • Effects for low and medium thyroid equivalent doses, typical of the range of doses received by the emergency workers, are difficult to quantify, and the potential for and magnitude of effects remains unclear. The intake of 131I via milk was also limited by the relatively low contribution of milk to the diet of infants and by the strict restrictions on the consumption of milk imposed by the authorities following the accident. Unwanted terminations of pregnancy attributable to the radiological situation have not been reported. While WHO estimates were generally higher than those of UNSCEAR, this was primarily because they were early dose projections based on very limited data following the accident. 99 Given the limited information available at the time, the assessment contained a number of conservative assumptions.
