Radium-226 has a half-life of 1,285 years. How long would it take for a sample of Radium-226 to reach 5 half-lives?

Answer:

6425 years

Explanation:

Half life refers to the time taken for a radioactive substance to decay to half of the original number of atoms present in the sample.

Some radioactive nuclides have short half lives while others have long half lives.

If 1 half life of Radium-226 is 1,285 years

Then, five half lives = 5 * 1,285 years = 6425 years
