What is the equivalent of 2 mm lead against to steel thickness when it comes to radiation shielding?

The equivalent thickness of lead for radiation shielding can vary depending on the type of radiation and energy levels involved. Generally, 2 mm of lead is approximately equivalent to about 1 cm (10 mm) of steel for gamma radiation shielding. This equivalence arises because lead is denser and more effective at attenuating radiation compared to steel. However, specific calculations may be necessary for different radiation types and energies, so consulting detailed shielding tables or standards is recommended for precise applications.
