👉 Hazardous light particles, often referred to as cosmic rays or high-energy galactic particles, pose significant health risks due to their high energy and ionizing radiation. These particles originate from outer space, primarily from supernovae and other violent cosmic events, and can penetrate deep into the human body upon entering through the atmosphere. Unlike lower-energy radiation such as X-rays or gamma rays, hazardous light particles have a high linear energy transfer (LET), meaning they deposit energy over a very short path, causing extensive damage to cellular DNA. This can lead to mutations, cell death, and an increased risk of cancer, particularly leukemia and solid tumors. Prolonged exposure to these particles, whether through space travel or living in high-radiation environments, can also cause acute radiation sickness, characterized by nausea, fatigue, and in severe cases, organ failure. Protective measures, such as shielding and limiting exposure time, are crucial to mitigate these hazards.
