What is phosphorus-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.
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 32P, giving a better resolution.
What does phosphorus-32 look like?
Phosphorus-32 ( 32 P) 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.

What are the main uses of phosphorus?
Uses of Phosphorus
Phosphorus is used in the manufacture of safety matches (red phosphorus), pyrotechnics and incendiary shells. Phosphorus is also used in steel manufacture and in the production of phosphor bronze. Phosphates are ingredients of some detergents. Phosphorus is used to make light-emitting diodes (LEDs).
How do humans use phosphorus?
Function. The main function of phosphorus is in the formation of bones and teeth. It plays an important role in how the body uses carbohydrates and fats. It is also needed for the body to make protein for the growth, maintenance, and repair of cells and tissues.

How much does phosphorus cost?
Cost of Phosphorus
The price of pure phosphorus is $0.3 per gram.
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’s the half-life of phosphorus 31?
Phosphorus
| Mass Number | Half-life | Decay Mode |
|---|---|---|
| 30 | 2.498 minutes | Electron Capture |
| 31 | STABLE | – |
| 32 | 14.262 days | Beta-minus Decay |
| 33 | 25.35 days | Beta-minus Decay |
What is phosphorus-32 half-life?
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).
What are the two major human uses of phosphorus?
It is essential for the creation of DNA, cell membranes, and for bone and teeth formation in humans. It is vital for food production since it is one of three nutrients (nitrogen, potassium and phosphorus) used in commercial fertilizer.
What are 5 physical properties of phosphorus?
Properties: The melting point of phosphorus (white) is 44.1°C, boiling point (white) is 280°C, specific gravity (white) is 1.82, (red) 2.20, (black) 2.25-2.69, with a valence of 3 or 5. There are four allotropic forms of phosphorus: two forms of white (or yellow), red, and black (or violet).
How does phosphorus look like?
Phosphorus (P), nonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.
What are the signs of phosphorus deficiency?
Symptoms of phosphorus deficiency include loss of appetite, anxiety, bone pain, fragile bones, stiff joints, fatigue, irregular breathing, irritability, numbness, weakness, and weight change. In children, decreased growth and poor bone and tooth development may occur.
What happens if you eat too much phosphorus?
Extra phosphorus causes body changes that pull calcium out of your bones, making them weak. High phosphorus and calcium levels also lead to dangerous calcium deposits in blood vessels, lungs, eyes, and heart. Over time this can lead to increased risk of heart attack, stroke or death.
What foods to avoid if phosphorus is high?
High Phosphorus Foods to Avoid or Limit:
- Dairy foods.
- Beans.
- Lentils.
- Nuts.
- Bran cereals.
- Oatmeal.
- Colas and other drinks with phosphate additives.
- Some bottled ice tea.
What are the symptoms of phosphorus deficiency?
Some medications can cause phosphorus levels to drop, including some antacids and diuretics (water pills). Symptoms of phosphorus deficiency include loss of appetite, anxiety, bone pain, fragile bones, stiff joints, fatigue, irregular breathing, irritability, numbness, weakness, and weight change.
What is unique about phosphorus?
Phosphorus is a poor conductor of heat and electricity, except black phosphorus. All types of phosphorus are solid at room temperature. The white form (sometimes called yellow phosphorus) resembles wax, the red and violet forms are noncrystalline solids, while the black allotrope resembles graphite in pencil lead.
How much phosphorus should I take daily?
The Food and Nutrition Board of the Institute of Medicine recommends a diet with 700 mg/day of phosphorus in healthy people, and 1250 mg/day in children and pregnant women [14].
How much does Phosphate cost per ton?
By December, the value of US diammonium phosphate (DAP) had added 58 percent to its value, rising from US$245 per metric ton (MT) to US$388.50.
How much does phosphorus cost per ton?
After accounting for nitrogen value, both fertilizers have phosphorus (as P2O5) currently priced at about 40 cents per unit. At $379 per ton, the price of potash (0-0-60/62) increased by 10 percent during the past year.
Can we live without phosphorus?
Phosphorus is an essential nutrient for all forms of life. It is a key element in our DNA and all living organisms require daily phosphorus intake to produce energy. It cannot be replaced and there is no synthetic substitute: without phosphorus, there is no life.
When a sample of phosphorus-32 is placed 1 cm from the detector?
When a sample of phosphorus-32 (a beta-emitter used to treat leukemia and pancreatic cancer) was placed 1 cm from the detector, the intensity of its radiation was measured to be 491 counts per second.
What is the difference between 31p and 32p?
Phosphorus-32 is known as a radioactive isotope of the phosphorus element. The nucleus of this isotope has 15 protons and 17 neutrons. There is also Phosphorus-31 which is the most common isotope of phosphorus. Therefore, the difference between them is one neutron more than the other.
