Radiation Shielding: How We Stay Protected

Radiation shielding blocks or reduces harmful ionizing radiation exposure.
Different types of radiation need different shields—paper stops alpha, metal stops beta.
Dense materials like lead and concrete are best for gamma rays and X-rays.
Hydrogen-rich materials, such as water or polyethylene, are effective against neutrons.
Spacecraft use specialized shielding to protect astronauts from cosmic radiation.
In nuclear reactors, thick concrete walls serve as powerful protective barriers.
Medical facilities rely on lead-lined rooms to safeguard staff during X-ray or radiation therapy.
Shielding design balances safety with cost, weight, and practicality.
Radiation exposure is measured in sieverts, guiding how much protection is needed.
Without effective shielding, modern nuclear power, medicine, and space exploration wouldn’t be possible.
