WitrynaThe importance of delayed neutrons to the controllability of the reactor cannot be overstated. Inherent reactor control is provided by negative reactivity feedback mechanisms. Control rods permit rapid shutdown. WitrynaA neutron is one of the subatomic particles that make up matter. The neutron has no electric charge and a rest mass equal to 1.67493 × 10 −27 kg — marginally greater than that of the proton but nearly 1839 times greater than that of the electron. The neutron has a mean square radius of about 0.8×10−15 m or 0.8 fm, and it is a spin-½ fermion. In …

Research in 2003 showed that 26% of proton therapy are for prostate cancer patient. In prostate cancer patients, medical practitioners found the different result regarding the proton treatment. WitrynaWhat do neutrons do? Left to themselves, they decay (after a while) into protons, electrons and antineutrinos. In nuclei, they help bind the nucleus against the mutual repulsion of all the protons. In neutron stars, they form the densest substance outside of black holes: neutronium.
