Phosphorus-32 is an energetic beta emitter
What are the benefits of using phosphorus-32?
Chromic phosphate P 32 is
used to treat cancer or related problems
. It is put by catheter into the pleura (sac that contains the lungs) or into the peritoneum (sac that contains the liver, stomach, and intestines) to treat the leaking of fluid inside these areas that is caused by cancer.
What diseases can phosphorus-32 diagnose?
A radioactive form of the element phosphorus. It is used in the laboratory to label DNA and proteins. It has also been used to treat a blood disorder called
polycythemia vera and certain types of leukemia
, but it is not commonly used anymore.
Is phosphorus 33 dangerous?
Phosphorus-33 Safety Precautions. Hazard: The beta radiation from mCi
quantities is not an external
radiation hazard. However, ingestion or inhalation may result in an internal exposure.
Is phosphorus-32 possible?
The nucleus of phosphorus-32 contains 15 protons and 17 neutrons, one more neutron than the most common isotope of phosphorus, phosphorus-31. … Phosphorus-32
only exists in small quantities on Earth
as it has a short half-life of 14 days and so decays rapidly.
What is the use of phosphorus 33?
Phosphorus-33
It is used in
life-science laboratories
in applications in which lower energy beta emissions are advantageous such as DNA sequencing. P can be used to label nucleotides. It is less energetic than
32
P, giving a better resolution.
Where does P-32 come from?
Phosphorus 32 (P-32) is the
phosphorus isotope
whose nucleus consists of 15 protons and 17 neutrons. It disintegrates by emitting a β- (1.71 MeV) particle in 32S with a half-life of 14.263 days. It is an artificial radioactive substance obtained by neutron bombardment of stable phosphorus.
What is the use of phosphorus 31?
Phosphorus-31 NMR spectroscopy is an analytical chemistry technique that uses
nuclear magnetic resonance (NMR) to study chemical compounds that contain phosphorus
. Phosphorus is commonly found in organic compounds and coordination complexes (as phosphines), making it useful to measure
31
P NMR spectra routinely.
How is phosphorus-32 given?
In Phosphorus-32 therapy,
an intravenous injection of radioactive phosphorus is taken up by the bone and bone marrow
. The Phosphorus-32 slows down or stops cell production from the bone marrow for a while.
What type of radiation does phosphorus-32 emit?
Phosphorus-32 is a commonly used radionuclide with a half-life of 14.3 days, emitting
beta particles
with a maximum energy of 1.71 MeV (Million Electron Volts). The beta particles travel a maximum of 20 feet in air at maximum energy.
Where is phosphorus-32 found in the body?
Phosphorus-32 radioactive isotope is actively used for biochemical studies. It is
embedded in nucleic acids involved in all metabolic processes of living bodies
and replaces stable phosphorus-31. As phosphorus-32 is a beta emitter, its movement within the body can be tracked using tomography.
What is the use of radioactive phosphorus?
Radioactive phosphorus (P-32) is a
type of internal radiotherapy
and is a treatment for some blood disorders, such as polycythaemia vera (PV) and essential thrombocythaemia (ET).
What is the half-life of phosphorus 33?
The radioactive isotope of phosphorus with relative atomic mass 32.971725, half-life of
25.34 days
and nuclear spin
1
/
2
.
What are the safety precautions of phosphorus?
Wear safety glasses, impervious gloves and a fire-retardant laboratory coat
. Control ignition sources and avoid dust formation. Avoid heat, shock and friction. Keep a supply of wet sand available in the work area and ensure there is a water/wet foam extinguisher immediately available.
What is the beta decay product of P 33?
Phosphorus-33 is a radioisotope of phosphorus that undergoes beta emission resulting in the formation of
Sulfur-33
.
How many protons does phosphorus-33 have?
21. Phosphorus-33 (atomic number 15) contains 18 neutrons/
18 protons
.
