Many protection measures rely on the use of lead. What is it about lead that makes it effective as a protective material?Group of answer choicesThe most common isotopes of lead are not radioactive, so it is not a source of radiation.Lead is corrosion resistant, and is not weakened by being continually exposed to radiation.Lead has a relatively low melting point and is ductile. This makes the casting of lead into shields easy.Lead has a high proton number and a high density. It is therefore very effective at attenuating radiation.Lead is relatively abundant making it the most cost effective material to use as a shielding.
