Lead aprons used in radiology primarily protect against what type of radiation?Question 51Select one:a.Alpha particlesb.Gamma raysc.Scatter radiationd.Beta particles

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.

Which form of nuclear radiation is extremely penetrating and can be only blocked by a block of lead that is several centimetres thick?

Lead-lined PPE is worn when there is:AAn animal that may biteBAny potential for exposure to radiationCAn infectious animalDA need to restrain an animal

Which radiations are not human friendlyQuestion 7AnswerA.Gamma rays and x-rayB.Visible and microwaveC.Microwave and infrared

Recall which radioisotope is often used in radiotherapy machines as a source of gamma rays.
