Can be stopped by lead

Lead is often used as a protective barrier against certain types of radiation, such as X-rays and gamma rays. Lead is a dense material that effectively absorbs these high-energy radiation particles, preventing them from passing through and reaching living organisms. Lead is commonly used in medical facilities as shielding for X-ray rooms and in nuclear power plants to contain radioactive materials. However, it is important to note that lead is not effective against all types of radiation. Some radiation, such as alpha particles and low-energy beta particles, can easily penetrate lead. Additionally, lead itself can be hazardous to human health if ingested or inhaled, so proper precautions should be taken when working with lead or lead-containing materials.
