Also asked, how many neutrons are in phosphorus?

16 neutrons

One may also ask, what is phosphorus 32 used for? 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.

Likewise, people ask, how is phosphorus 32 produced?

In the laboratory, P-32 can be produced (even as an experiment with students) using the S-32 (n, p) P-32 reaction with fast neutrons. A sample of pressed elemental sulfur is placed close to a neutron source for several days. After that, the sulfur is washed with boiling water.

What type of radiation does phosphorus 32 emit?

beta particles

Is Phosphorus 32 dangerous?

Safety. The high energy of emitted beta particles and the low half-life of phosphorus-32 make it potentially harmful; its maximum specific activity is 338 TBq/mmol (9131 Ci/mmol).

Where is phosphorus found?


Phosphorus is not found in its pure elemental form on Earth, but it is found in many minerals called phosphates. Most commercial phosphorus is produced by mining and heating calcium phosphate. Phosphorus is the eleventh most abundant element in the Earth's crust. Phosphorus is also found in the human body.

What is radioactive phosphorus used for?

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).

Is white phosphorus radioactive?

Yes, there are many isotopes of Phosphorus, all of them radioactive except Phosphorus-31. The longest, Phosphorus-32, has a half life of about 30 days, and there's no native way to make it from primordial isotopes, so for all practical purposes, native phosphorus is monoisotopic and non radioactive.

Is Phosphorus a metal?

Phosphorus is a non-metal that sits just below nitrogen in group 15 of the periodic table. This element exists in several forms, of which white and red are the best known.

What is white phosphorus in?

White phosphorus munitions are weapons which use one of the common allotropes of the chemical element phosphorus. White phosphorus is used in smoke, illumination and incendiary munitions, and is commonly the burning element of tracer ammunition.

Why is phosphorus 32 suitable for use as a tracer?


(c) Phosphorus-32 is a radioactive isotope that emits beta radiation. Watering the root system of a plant with a solution containing a phosphorus-32 compound can help scientists to understand the growth process. Explain why phosphorus-32 is suitable for use as a tracer in this situation.

Where is carbon 14 found?

The primary natural source of carbon-14 on Earth is cosmic ray action on nitrogen in the atmosphere, and it is therefore a cosmogenic nuclide.

How do you calculate the half life of phosphorus 32?

Question: The half-life of phosphorus-32 is 14.26 days. The decay constant is k=4.86×10−2/days k = 4.86 × 10 − 2 / d a y s . If you accidentally spill phosphorus-32 onto your shoe, how long would it take before 99.9% of the radioactive material has decayed so that you can safely wear the shoes again?
