#### Answer

No, the amount of radioactive material remaining after two months is one-fourth of the original.

#### Work Step by Step

After one half-life, we are down to one-half the original amount.
After two half-lives, we are down to one-quarter the original amount.
After three half-lives, we are down to one-eighth the original amount.
After four half-lives, we are down to one-sixteenth the original amount.
Each month, half of the remaining atoms will decay.
