Forms of Radiation

Which type of radioactive emission has a positive charge and weak penetrating power?

• alpha particle

• beta particle

• gamma ray

• neutron

Which of these types of nuclear radiation has the greatest penetrating power?

• alpha

• neutron

• beta

• gamma

Compared to the mass and the penetrating power of an alpha particle, a beta particle has

• less mass and greater penetrating power

• less mass and less penetrating power

• more mass and greater penetrating power

• more mass and less penetrating power

Alpha particles and beta particles differ in

• mass, only

• charge, only

• both mass and charge

• neither mass nor charge

Which nuclear decay emission consists of energy, only?

• alpha particle

• beta particle

• gamma radiation

• positron

Which particle has the least mass?

• alpha particle

• beta particle

• neutron

• proton

In order of most to least penetrating radiation we have

• Alpha , Beta,  Gamma
• Beta , Gamma , Alpha
• Gamma, Beta, Alpha
• Gamma, Alpha, Beta

What type of radiation can be stopped by a piece of paper?

• Alpha radiation
• Beta radiation
• Gamma radiation

What type of radiation can be stopped by a approximately 5 cm of air?

• Alpha radiation
• Beta radiation
• gamma radiation

What type of radiation can be stopped by a 5 mm piece of aluminium?

• Alpha radiation
• Beta radiation
• gamma radiation
