Nuclear power does present some potential health risks, but it's important to consider these in context:

1. Radiation exposure: Accidents can release radioactive materials, which can cause radiation sickness, cancer, and genetic damage.

2. Waste management: Long-lived radioactive waste requires secure storage for thousands of years, posing potential future health risks if not properly contained.

3. Mining impacts: Uranium mining can expose workers and nearby communities to radon gas and other radioactive particles.

4. Thermal pollution: Cooling water discharge from nuclear plants can affect aquatic ecosystems.

However, modern nuclear power plants are designed with multiple safety systems. The risk per unit of energy produced is generally lower than fossil fuels. Proper regulation, waste management, and emergency preparedness can mitigate many concerns.

It's crucial to weigh these risks against those of other energy sources and consider comprehensive energy policies that balance safety, cost, and environmental impact. Continuous improvements in reactor design and waste disposal methods are also reducing risks over time.
