Nuclear radiation can be used to look for flaws in metal parts of bridges. The process is similar to using Xrays to look at human bones. What type of radioactive decay would work best for this test? Explain your answer.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
