Radioactivity

A radiation source emitting a highly permeating energy could be producing either an X-ray or a(n) _

• alpha (α) ray

• beta (β) ray

• gamma (γ) ray

Which radiation produces particles with the highest mass?

• alpha (α) ray

• beta (β) ray

• gamma (γ) ray

Which type of radiation has particles partially made of neutrons?

• alpha (α) ray

• beta (β) ray

• gamma (γ) ray

Which radiation would be repelled by a positive charge?

• alpha (α) ray

• beta (β) ray

• gamma (γ) ray

Marie Curie used a magnet and a charge (both positive and negative) and failed to affect the direction of which type of radiation?

• alpha (α) ray

• beta (β) ray

• gamma (γ) ray

Alpha radiation or waves were found to be streams of charged particles that were identical in mass and charge to atomic nuclei of which element?

• lithium (Li)

• uranium (U)

• helium (He)
