Explanations:The question asks about the highly radiated place in Kerala. The correct answer is Karunagapally, which is a place in the Kollam district of Kerala. Karunagapally is known for its high levels of natural radiation due to the presence of thorium in the soil. Thorium is a naturally occurring radioactive element that is found in the soil and rocks of certain areas. The presence of thorium in the soil of Karunagapally leads to higher levels of radiation in the area compared to other parts of Kerala.
Thorium is a naturally occurring radioactive element that is found in small amounts in the earth's crust. It is a weakly radioactive element that decays into other radioactive elements, including radium and radon. The decay of thorium releases alpha particles, which are a form of ionizing radiation. The presence of thorium in the soil of Karunagapally leads to higher levels of radiation in the area, making it a unique geographical location in Kerala.
It is important to note that while Karunagapally has higher levels of natural radiation, the levels are still within safe limits for human habitation. The radiation levels in Karunagapally are monitored regularly to ensure the safety of the residents. The unique geological features of Karunagapally make it an important location for studying natural radiation and its effects on the environment and human health.
The other options listed in the question, such as Kundara, Punalur, and Chavara, are not known for high radiation levels. These places are located in different parts of Kerala and do not have the same geological features as Karunagapally. Therefore, they are not the correct answer to the question.
