Which part of the human body does radiation primarily attack?

Radiation primarily targets the central nervous system due to its sensitivity to damage from radiation. The brain and spinal cord contain rapidly dividing cells during development, which makes them particularly vulnerable to the effects of radiation exposure. Damage to these cells can lead to a range of neurological problems and disorders, which can be serious or even life-threatening.

Additionally, the central nervous system plays a crucial role in overall bodily functions, and when affected by radiation, it can disrupt essential processes such as motor control, sensory perception, and cognitive functions. This vulnerability is further evidenced by research indicating that central nervous system tissues have a higher risk of developing conditions like radiation-induced tumors.

While other systems in the body can also be affected by radiation, such as the heart, lungs, and digestive system, the central nervous system is uniquely at risk due to its structure and the critical functions it performs. Thus, the central nervous system is the correct choice as it highlights the significant impact of radiation exposure on this critical area of the human body.
