What is P 32 used for?
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 P 32 stable?
Only one is stable, P-31, making phosphorus a monoisotopic element. Longer-lived phosphorus radioisotopes are phosphorus 33 (P-33) (half-life of 25.34 days) and phosphorus 32 (P-32) (14.263 days). All other isotopes have a half-life of less than 2.5 minutes, and most of them less than one second.
What does P 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 1.71MeV. The beta particles travel a maximum of 20 feet in air.
What is p32 in chemistry?
Phosphorus P-32 is a radioactive isotope of phosphorus with beta particle-emitting radiocytotoxic activity.
Where can Phosphorus-32 be found?
Phosphorus is found in many organic molecules and so phosphorus-32 has many applications in medicine, biochemistry, and molecular biology where it can be used to trace phosphorylated molecules (for example, in elucidating metabolic pathways) and radioactively label DNA.
How is phosphorus-32 given?
Phosphorus-32 (P-32) therapy is where an intravenous injection of radioactive phosphorus is taken up by the bone and bone marrow. The P-32 slows down or stops cell production from the bone marrow for a while.
Is phosphorus-32 Harmful?
Phosphorus-32 is an energetic beta emitter which can penetrate up to 0.8 cm into living skin tissue. Therefore, this isotope poses an external (skin) dose hazard to persons as well as a potential internal hazard.
What does phosphorus-32 look like?
Phosphorus-32 (32P) is a radioactive isotope of phosphorus. 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.

What is p32 in biology?
p32/gC1qR/C1QBP/HABP1 is a mitochondrial/cell surface protein overexpressed in certain cancer cells. The p32 knockdown cells exhibited reduced synthesis of the mitochondrial-DNA-encoded OXPHOS polypeptides and were less tumorigenic in vivo.
How is phosphorus-32 disposed?
Waste Disposal Liquid Wastes: through the Sewer Disposal Program. The laboratory disposal limit for P-32 is 0.3 mCi per month.
What does the number 32 mean to you?
The number 32 is usually seen as a number that represents the social, friendships and even business relationships, always showing the good relationship between peers.
What is the significance of 32 in Computer Science?
The number 32 is of great importance, as we have seen, apart from the ten sephiroths and the twenty letters of the Chaldean alphabet, it is also a quantity that when used in computing, we see that the kb. They are not 1000 bits, but 32 squared, this is 1024 bits.
What is the difference between MW and kW?
Watts, therefore, measure instantaneous power while watt- hours measure the total amount of energy consumed over a period of time. A megawatt (MW) is one million watts and a kilowatt (kW) is one thousand watts. Both terms are commonly used in the power business when describing generation or load consumption.
How is the nominal power of PV devices measured?
The nominal power of PV devices is measured under standard test conditions (STC), specified in standards such as IEC 61215, IEC 61646 and UL 1703. Specifically, the light intensity is 1000 W/m 2, with a spectrum similar to sunlight hitting the earth’s surface at latitude 35°N in the summer ( airmass 1.5), the temperature of the cells being 25 °C.
