It might take a millisecond, or it might take a century. But if you have a large enough sample, a pattern begins to emerge.It takes a certain amount of time for half the atoms in a sample to decay.Bennett, a senior in college, and Thompson, a junior in high school, didn’t think about dating each other when they first met.
Based on the formula, a 21-year-old could date someone as young as 17, an 18-year-old could be with a 16-year old, and a 16-year-old with a 15-year-old.
Having a partner who is much older or younger has become somewhat trendy in today’s celebrity-obsessed culture, perhaps even more so among young adults.
The rule is that a sample is safe when its radioactivity has dropped below detection limits. So, if radioactive iodine-131 (which has a half-life of 8 days) is injected into the body to treat thyroid cancer, it’ll be “gone” in 10 half-lives, or 80 days.
This stuff is important to know when using radioactive isotopes as medical tracers, which are taken into the body to allow doctors to trace a pathway or find a blockage, or in cancer treatments.
Even our majors, or in her case future major, were alike. She didn’t jump to conclusions like I (thought) she would’ve. as she asked questions.” The couple has been together for two years and never thinks about their age difference.
“To be honest, if (Mia) never told me her age, I would have thought that she was close to the same age as me,” Bennett said.
Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay.
A useful application of half-lives is radioactive dating.
As long as an organism is alive, the amount of C-14 in its cellular structure remains constant.
