Radioactivity Word Search

Radioactivity is a topic covering ionizing radiation or particles caused by interactions of an atomic nucleus. This radioactivity word search contains 24 different glossary terms covering radiation and radioactivity.

Radioactivity Word Search

These radioactivity vocabulary terms can be found hidden horizontally, vertically, and diagonally both forward and reverse. The word search fits nicely on a standard 8 1/2″ x 11″ sheet of paper. If you are printing to A4 paper, the puzzle scales down nicely when “Fit to Page” is selected in the print options.
