Gizmo Warm-up 
While most atoms are stable, some are radioactive, which means that they have a tendency to undergo 
spontaneous nuclear decay. The decay of radioactive atoms generally results in the emission of particles 
and/or energy. Several types of nuclear decay can be explored with the Nuclear Decay Gizmo. On the 
Gizmo, check that Alpha decay and Uranium are selected. 
1. Click Play ( ), and then click Pause ( ) when the alpha particle is clearly visible. What is an alpha 
particle made o...

How do nuclear gauges work? Why does so much care need to be taken when using them? - AnswerNuclear gauges use the interaction of radiation with matter to measure the density and moisture of 
material. Radiation sources within each gauge transmit radiation through the test material. Detectors 
contained in the gauge measure the radiation that is scattered by the test material or that passes 
through it. By calculating the percentage of radiation that reaches the detectors, the gauge can 
determi...
