What do humans use neptunium for?
While neptunium itself has no commercial uses at present, it is used as a precursor for the formation of plutonium-238, and in radioisotope thermal generators to provide electricity for spacecraft. Neptunium has also been used in detectors of high-energy neutrons.
What are some uses for the element neptunium?
Neptunium has been used in neutron detectors. It does not have any commercial application. Neptunium occurs naturally in Earth, being present in minute quantities in uranium ores. Today neptunium-237 is extracted in kg quantities from the spent uranium fuel rods of nuclear reactors.
Does the human body use neptunium?
Neptunium has no known biological role. It is toxic due to its radioactivity. Neptunium is obtained as a by-product from nuclear reactors. It is extracted from the spent uranium fuel rods.
How much does neptunium cost?
This isotope can be used as a component in neutron detection instruments. It is offered at a price of $280/g.
Can you eat neptunium?
Neptunium can be taken into the body by eating food, drinking water, or breathing air. Gastrointestinal absorption from food or water is a likely source of internally deposited neptunium in the general population.
How is neptunium-237 used?
Neptunium-237, which is produced in gram quantities as a by-product of the production of plutonium in nuclear reactors, is used in neutron detectors.
What element has an atomic mass of 237?

How is NP 237 produced?
Neptunium 237 is routinely produced in nuclear reactors as a result of the neutron irradiation of uranium 235 and uranium 238, the two most common constituents of nuclear fuel. It is also a decay product of americium 241. Large quantities of neptunium 237 are found in spent nuclear fuel.
Does neptunium exist in nature?
Though traces of neptunium have subsequently been found in nature, where it is not primeval but produced by neutron-induced transmutation reactions in uranium ores, American physicist Edwin M. McMillan and chemist Philip H.
Can I buy neptunium?
And, while researching how to best score certain elements, you learn that, while it’s generally illegal to buy neptunium, you can get a sample by buying a 30-year-old smoke detector that uses americium, which eventually decays into neptunium.
What are 5 interesting facts about neptunium?
It has five oxidation states, +3 to +7, each with a different colour in solution, ranging from violet to yellow green. It has no stable isotopes. Instead, it has 20 radioisotopes with a range of half-lives and mass numbers 225 to 244. Its longest living isotope is neptunium-237, with a half-life of 2.14 million years.
Can you legally buy francium?
Fast Facts: The Most Expensive Natural Elements The most expensive natural element is francium, but it decays so quickly it can’t be collected to be sold. If you could buy it, you’d pay billions of dollars for 100 grams.
How do you collect elements?
Depending on your interests, here are some different ways of putting together an element collection:
- Buy a ready-made set.
- Buy My Poster.
- Buy Elements from a Chemical Supplier.
- Scrounge around on eBay, at Walmart, Hardware stores, etc.
- Collect periodic table posters instead.
- Read a book.
What are some compounds that are made from neptunium?
Neptunium also forms a number of more traditional compounds, such as neptunium dioxide (NpO 2 ), neptunium trifluoride (NpF 3 ), and neptunium nitrite (NpNO 2 ).
Can you own neptunium?
