These radioactive elements find their way into the state's water bodies, including groundwater and surface water, posing significant health risks to the local population.

Groundwater, a vital source of drinking water for many communities in Kerala, is particularly susceptible to radioactive contamination. The state's geological composition, characterized by ancient rock formations, provides a natural pathway for these radioactive elements to seep into the ground. Over time, the accumulation of radium and thorium in the soil and water can lead to elevated levels of radioactivity, making the water unsafe for consumption without proper treatment.

Surface water, such as rivers and lakes, is also at risk. Industrial activities, particularly those involving mining and mineral processing, can release radioactive materials into nearby water bodies. Additionally, improper waste disposal practices, including the dumping of radioactive waste, further exacerbate the problem. As a result, the water sources that are supposed to provide a steady supply of clean water for irrigation, domestic use, and industrial processes become contaminated, leading to potential long-term health consequences for the residents.

The impact of radioactive pollution on water sources is twofold. Firstly, it poses a direct threat to human health. Consuming water with elevated levels of radioactivity can lead to various health issues, including increased risks of cancer, bone disorders, and other radiation-related diseases. Secondly, the contamination affects the overall water quality, making it unsuitable for various purposes, including agriculture and industrial processes, which can have economic repercussions for the region.

Addressing this issue requires a multi-faceted approach. It involves implementing strict regulations on industrial waste disposal, conducting regular water quality monitoring, and investing in advanced water treatment technologies. Public awareness campaigns can also play a crucial role in educating the community about the risks associated with radioactive pollution and promoting the adoption of safe water practices. By taking these measures, Kerala can work towards mitigating the impact of radioactive elements on its water sources and ensuring a healthier environment for its residents.
