Which of the following is emitted by Phosphorus 32?
**Core Concept**
Phosphorus-32 is a radioactive isotope of phosphorus that emits a specific type of ionizing radiation, which is used in various medical and scientific applications. This radiation is a result of the radioactive decay of phosphorus-32 into sulfur-32.
**Why the Correct Answer is Right**
Phosphorus-32 emits beta particles, which are high-energy electrons emitted from the nucleus of the atom during beta decay. This process involves the conversion of a neutron in the nucleus to a proton and an electron, resulting in the emission of a beta particle. The beta particles emitted by phosphorus-32 have a maximum energy of approximately 1.7 MeV and a half-life of 14.29 days.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Phosphorus-32 does not emit alpha particles, which are high-energy helium nuclei. Alpha particles are emitted by different radioactive isotopes, such as radon-222.
**Option B:** This option is incorrect because Phosphorus-32 does not emit gamma rays, which are high-energy electromagnetic radiation. While phosphorus-32 does emit beta particles, it does not emit gamma rays.
**Option C:** This option is incorrect because Phosphorus-32 does not emit X-rays, which are low-energy electromagnetic radiation. X-rays are produced by other medical devices, such as X-ray machines, but not by radioactive isotopes like phosphorus-32.
**Clinical Pearl / High-Yield Fact**
Phosphorus-32 is commonly used in medical research and therapy, particularly in the treatment of certain types of leukemia and other cancers. Its beta-emitting properties make it useful for targeted radiation therapy.
**Correct Answer:** C. Beta particles.
