Question

your medical practitioner has advised you to take up a diagnostic test. you are given three radioactive cookies, for the diagnostic purposes: i. an alpha emitter ii. a beta emitter iii. a gamma emitter which cookie will pass through your body easily? i alone ii and iii iii alone i and iii

Explanation:

Gamma rays have the highest penetrating power among alpha, beta, and gamma radiations. Alpha particles have very low penetrating power (can be stopped by a sheet of paper or outer layer of skin). Beta particles have moderate penetrating power (can be stopped by a few millimeters of aluminum). Gamma rays can pass through thick layers of materials like concrete and lead to some extent and can easily pass through the human body compared to alpha and beta emissions.

Answer:

III alone
