Thanks for the feedback!
It is a nuclear reaction: Radium(alpha,neutrons)Beryllium.
The Half-Life source is proprietary. There is no way to legally obtain the source code, unless you work for Valve. To get the game Half-Life: Source, install Steam, , buy th…e game for $10, then install the game.
the element that can be used as a neutron source is beryllium
That's what I have been looking for. Please help me in answering this question.... PLEASE! >:( IM BEGGING YOU! :0
The Iphone 5C is Iphone 5Colorful 5c can also stand for thenumber 500 ("c" is the Roman numeral for 100) or for 5 degreesCelsius (centigrade) . +++ . "5c" can not stand fo…r any Roman numerals forthree reasons. For a start you do not mix Arabic and Roman numeralslike that - it would be nonsensical. Secondly, the Roman for 100 is capital " C ", but thirdly, in the Romanscale, 5 is V, 50 is L and 500 is D. The ' C ' isalso capital for degrees Celsius / Centigrade.
neutrons are produced at a rate of 2.8x10+6 neutrons/second/curie Am-241 for an optimally, well mixed source of americium and beryllium. the neutron dose rate of a one curi…e Am-Be source would be 34.7 mR/hr (or 347 µSv/hr) at 30 cm. the gamma dose rate of a one curie Am-Be source would be 0.17 mR/hr (or 17 µSv/hr) at 30 cm. americium-241 also decays by spontaneous fission with a half life of 2x10+14 years, producing 0.18 neutrons/second/curie Am-241. note that beryllium is not required for this neutron production mechanism.
From the steam store, it only costs 10 US dollars. store.steampowered.com
Uranium-235 undergoes a small rate of natural spontaneous fission, so there are always some neutrons being produced even in a fully shutdown reactor. When the control rods are… withdrawn and criticality is approached the number increases because the absorption of neutrons is being progressively reduced, until at criticality the chain reaction becomes self sustaining. Note that sometimes a neutron source is provided in the reactor, but this is not essential to start the chain reaction, it is to give a shutdown neutron population which is detectable by instruments and so make the approach to critical more observable. The reactor will go critical at the same control rod position whether a source is loaded or not.
A neutron star no longer produces energy - it is a dead star. It will gradually get colder, until it stops emitting any significant amount of heat. Any heat the neutron star r…adiates is residual heat - heat that was produced earlier, either through fusion, or through the tremendous gravitational collaps that produced the neutron star.
If you mean the 5 C's, like you learn in school and such, it's Cotton Citrus Copper Climate Cattle
A neutron source. Examples are: Polonium alpha source, beryllium absorbs alpha and emits neutron.Radium alpha source, beryllium absorbs alpha and emits neutron.Electrically a…ctivated tritium fusion neutron source.etc. For a bomb the source must emit roughly 10 neutrons during the nanosecond of maximum supercriticality (10 billion neutrons per second) to prevent a fizzle and maximize yield. For a reactor in startup a much less intense source is needed but it must be continuous (the source in the bomb can be a short pulse).
To get the chain reaction started at the right time relative to the assembly of the supercritical mass. Like ignition timing in a car's engine, you don't want it too early or …too late. In an atomic bomb too early severely reduces yield, too late runs the risk of spontaneous fission starting the chain reaction giving melting of the bomb and a fizzle.
5cc? cc means cubic centimetres which is equal to ml, so 5ml. if you mean cl, then that is equal to 50ml
The neutron source in a typical reactor is Antimony pins inside beryllium sleeves The antimony emits gamma rays and the beryllium converts the gamma rays to neutrons. The …neutrons place the in core instrumentation onscale so that criticality can be approached slowly and safely.
