The equation for the alpha decay of 233Pu:
94233Pu --> 92229U + 24He2+
where the alpha particle is represented as a helium nucleus.
Note that 233Pu decays by alpha decay with a probability of only 0.12%. The other 99.88% is Beta+ decay.
The beta decay of uranium-237 can be represented by the equation: (^{237}{92}U \to ^{237}{93}Np + e^- + \bar{\nu_e}) where (^{237}{92}U) decays into (^{237}{93}Np), an electron (e^-), and an electron antineutrino (\bar{\nu_e}).
The new atom formed from the decay of Neptunium-237 is Protactinium-233. After emitting an alpha particle (Helium-4 nucleus), a beta particle (electron or positron), and a gamma ray (photon), Neptunium-237 transmutes into Protactinium-233.
187mL equates to 6.32 US fluid ounces.
The most commonly used radioactive fuel is Plutonium (Pu) 238, which is alpha active and produces a useful amount of thermal energy, without the need for much shielding. This material is produced from Neptunium 237, which is separated out from spent reactor fuel. The Pu238 is assembled with a thermocouple array to produce a small amount of electricity, and is widely used in satellites if solar panels are not viable. Pu 238 has a half life of 87 years, so can power applications where the mission lasts a long duration. Other materials have been used, amongst them Strontium 90, but Pu238 is now the favourite. Wikipedia has entries giving more information-see 'Nuclear Fuel' section 8
1 ounce equals 28 grams. So 237 G. / 28 = 8.464 or 8-1/2 Ounces rounded up!
The beta decay of uranium-237 can be represented by the equation: (^{237}{92}U \to ^{237}{93}Np + e^- + \bar{\nu_e}) where (^{237}{92}U) decays into (^{237}{93}Np), an electron (e^-), and an electron antineutrino (\bar{\nu_e}).
Emitting alpha particles Am-241 decay to Np-237.
Americium-241 undergoes alpha decay to become Neptunium-237. During alpha decay, an alpha particle (two protons and two neutrons) is emitted, resulting in the conversion of Americium-241 to Neptunium-237.
The decay products of americium-241 include neptunium-237, plutonium-241, and various isotopes of neptunium, plutonium, and uranium. These decay products are formed as americium-241 undergoes alpha decay and transforms into new elements through a series of radioactive decays.
The alpha decay of americium-241 produce neptunium-237.
Uranium-237 will undergo beta minus decay to neptunium-237 according to the following equation: 92U237 => 93Np237 + e- + 0.519 MeV At the risk of being a bore, a neutron in U237 undergoes a weak interaction-mediated change into a proton and an electron. The electron will be ejected from the nucleus immediately. Along with the electron, which leaves with a lot of kinetic energy, we'll see an antineutrino and the decay energy (0.519 MeV).
alpha
The intermediate product is neptunium 237 ( a very long-lived radioisotope).
Uranium-237 has 142 neutrons. This can be determined by subtracting the atomic number (92) from the atomic mass (237) of uranium-237.
Npn decays to Pan-4 and alpha. Only isotopes 234, 235, and 237 of neptunium can undergo alpha decay, the others decay by beta-, beta+, K capture, and/or gamma decay. So the only products of neptunium alpha decay can be protactinium isotopes 230, 231, or 233.
For example americium-241 decay to neptunium-237 and americium-243 decay to neptunium-239.
A:Uranium - 238 --> Pb - 206 + Alpha + Beta note this is a simplified over all reaction, the actual process involves around 15 steps...A:The equation for the alpha decay of 238U is: 92238U --> 90234Th + 24HeThe alpha particle is represented as an He nucleus.
