Question

Carbon-14 has a half-life of 5,730 years. if the age of an objectolder than 50,000 years cannot be determine by radiocarbon dating,the

A) Carbon-14 levels on a sample are undetectable after approoximately fourteen half-lives

B) Carbon-14 levels in a sample are undetectable after approximately non half-lives

C) The half-lives of carbon-14 is too long to accuurately date the object

D) A radioisotope with a shorter half-lives should be used be used to date the object
@_lilb_to_smooth_4_U_ can you help me

Answer 1

@Tazmaniadevil you can help me

Answer 2

is this a homework question?

Answer 3

im not sure but B) is what i think @youngnephew34

Answer 4

yeah @Smartwizard

Answer 5

Although the half-life of carbon-14 makes it unreliable for dating fossils over about 50,000 years old, there are other isotopes scientists use to date older artifacts. These isotopes have longer half-lives and are found in greater abundance in older fossils. Some of these other isotopes include: Potassium-40, Uranium-235, Uranium-283, thorium-232, and Rubidium-87.
