Question

Which one is used for dating archaeological specimens like bones, shells and wood?
A) H-3
B) C-14
C) I-121
D) P-32

Answer 1

Hint: Archaeological specimens or sources are basically the material evidence like historical buildings, coins, inscriptions and other remains that gives important and detailed information pertaining to a particular period.

Complete Answer:
1. H-3 or Tritium or hydrogen-3 is an unprecedented and radioactive isotope of hydrogen. The nucleus of tritium (once in a while referred to as a triton) carries one proton and neutrons, while the nucleus of the not unusual place isotope hydrogen-1 (protium) consists of simply one proton, and that of hydrogen-2 (deuterium) consists of one proton and one Tritium is used as a tracer for biochemical research, animal metabolism research and floor water shipping measurements.

 2. I-121 Radioiodine therapy is a nuclear medicine treatment for an overactive thyroid, a condition called hyperthyroidism, and also may be used to treat thyroid cancer.

3. The radiation emitted with the aid of using phosphorus-32 may be used for healing in addition to diagnostic purposes

4. The most normally utilized radiometric dating strategy is radiocarbon dating. It is also referred to as carbon-14 and C-14 dating. This system is utilized to date the remaining parts of natural materials. These dating assessments are commonly done on charcoal, wood, bone, or shell, but any tissue that becomes ever alive may be dated.

So, the correct answer is option is (B) C-14.

Note: Chemist Willard Libby first found out that carbon-14 may want to act like a clock inside the 1940s. He gained the 1960 Nobel Prize in Chemistry for developing with the method. By emitting an electron and an electron antineutrino, one of the neutrons in the carbon-14 atom decays to a proton and the carbon-14 (half-life of 5,700 ± 40 years).
