The penetration power of electromagnetic radiation is related to its energy. Gamma rays are high-energy photons with very short wavelengths, allowing them to penetrate dense materials like thick lead or concrete. X-rays also have high penetration power, but generally less than gamma rays. Radio waves and infrared rays are part of the electromagnetic spectrum with much lower energy and thus much lower penetration power.
Following radiation has the highest penetration power.
