The half life of thorium-232 is 1,405(6).10e10 years.
The cost of 5 grams of thorium varies depending on the supplier, but on average, it can range from $100 to $300 per gram. Therefore, 5 grams of thorium can cost between $500 to $1500.

An ounce of marijuana (or any matter) is approximately 28 grams. A half ounce would then be 14 grams.
Half of a quarter ounce (which is 7 grams) of methamphetamine would weigh 3.5 grams.
A half gram of heroin weighs 0.5 grams.
After 2 half-lives, 25% of the original amount of thorium-234 will remain. This is because half of the substance decays in each half-life period.
Thorium-234 has a half-life of 24.1 days. How much of a 100-g sample of thorium-234 will be unchanged after 48.2 days?
