Question
Match the resulting effects and characteristics of ionizing radiation with the appropriate radiation source: Note: If any part of this question is answered incorrectly, a single red X will appear, indicating that one or more phrases are sorted incorrectly.
Alpha Particles Beta particles Gamma Photons(rays)
sort these under each catergory:
slightly penetrates the skin
cause a shallow sunburn like burn if the skin is exposed for an extended period
unable to readily penetrate the skin
only internal exposure can lead to considerable damage to nearby cells
penetrate deeplly into bone organ and tissues
most dangerous form of ionizing radiation, causes widespread damage
these particles are the largest in size and slowest moving particles
Explanation / Answer
Alpha Particles
Radiation Source: Alpha decay of very havy nuclei such as 241Am
Beta Rays
Radiation source: Beta decay from nuclei which contain an excess of the respective nucleon
Gamma Rays
Radiation Source: excited nuclei in their transition to lower nuclear energy levels
