The correct answer is "two examples of how radar installations might cause hazard to human health are: decreased ability to perform mental tasks and induction of eye cataracts".
Explanation:
According to the World Health Organization electromagnetic fields below 10 Gigahertz of power do not represent a threat to human health, which make most radar installations safe for operation. However, some studies performed in primates by the exposure of increasing levels of electromagnetic fields have shown that they can developed a decreased ability to perform mental tasks and induction of eye cataracts. This is explained by the exposure of electromagnetic fields that can increase the animals' body temperature by one centigrade.
