When neptunium-239 undergoes a beta decay what is the resulting atom?
plutonium-239
Neptunium-239 in turn undergoes beta decay, being transformed into plutonium-239 (atomic number 94).
What is the beta decay of neptunium-237?
The primary decay mode for the isotopes heavier than Np-237 is by beta-decay, forming plutonium. Neptunium-237, after decaying to protactinium then to uranium, eventually decays to form bismuth-209 and thallium-205.
How neptunium-239 is formed?
Trace amounts of the neptunium isotopes neptunium-237 and -239 are found naturally as decay products from transmutation reactions in uranium ores. In particular, 239Np and 237Np are the most common of these isotopes; they are directly formed from neutron capture by uranium-238 atoms.
What does neptunium decay into?
It decays into protactinium-233 through alpha decay. 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.
When 238 undergoes beta decay The product is NP 239?
Plutonium-239 is used as a fuel in breeder reactions. It can be formed from uranium-238. The process involves reacting uranium-238 with a neutron to produce uranium-239, which then undergoes beta decay to form neptunium-239, which undergoes further beta decay to give plutonium-239.
What is the half-life of neptunium-239?
2.36 days
Nuclear Waste Neptunium (Np, atomic number 93) is the first transuranic element. Neptunium-239 (half-life 2.36 days) occurs as an intermediate in the formation of plutonium from uranium but is too short-lived to be of concern in most wastes.
How does plutonium-239 decay?
Plutonium-239 decays through spontaneous fission while emitting alpha particles.
What is neptunium 237 used for?
However, neptunium-237 is used to create plutonium-238, which is then used in special energy generators that can power satellites, spacecraft and lighthouses for a long period of time. Neptunium-237 is also used in nuclear physics research as a part of a device that detects high-energy neutrons.
What particle is produced by the decay of uranium-239 to neptunium-239?
beta particle
The U-239, in turn, decays by emitting a beta particle to neptunium-239, which gives off another beta particle. Since each beta decay turns a neutron into a proton, these two beta decays suffice to turn a uranium atom into one of plutonium.
