In a critical mass, the material involved starts to undergo fission because of the presence of a dense neutron flux. The fission produces neutrons, which add to the neutron flux. This causes a great release of heat.
Reaching critical mass does not imply a powerful nuclear explosion. A powerful nuclear explosion develops when critical mass is attained for a long enough time for the majority of the nuclear material to get involved. This is a very tricky thing to do and does not happen accidentally. What can happen accidentally is a nuclear "pop," a sort of small explosion which throws the material apart, destroying the critical mass, and possibly producing a lot of pollution. (This was not what happened at Chernobyl, which was steam and chemical.)

What is the smallest amount of radioactive material that will support a self sustained reaction?
The smallest amount of radioactive material that can support a self-sustained nuclear reaction is called the "critical mass." This mass varies depending on the type of fissile material, such as uranium-235 or plutonium-239, and the configuration of the material. For instance, the critical mass for uranium-235 in a spherical shape is about 52 kilograms. This threshold is crucial for achieving a sustained chain reaction in nuclear fission.
What is the amount of fissionable material required to continue a reaction at a constant rate?
The amount of fissionable material required to sustain a nuclear reaction at a constant rate is determined by the material's critical mass. The critical mass is the minimum amount of fissionable material needed to sustain a chain reaction, and it varies depending on the material and the reactor design. By controlling factors such as neutron moderation and absorption, reactor operators can adjust the critical mass to maintain a steady reaction rate.
The smallest amount of a fissionable material that will give a self-sustaining chain reactions is called the?
The smallest amount of a fissionable material that will produce a self-sustaining chain reaction is called the critical mass. This mass of affected by geometry and other factors such as temperature, pressure, and moderator.
What is not a factor in determining critical mass is?
The color of the bicycles is not a factor in determining critical mass. Critical mass refers to the minimum number of participants needed for a collective action to be effective, typically in the context of a protest or demonstration involving cyclists. The factors that do influence critical mass include the number of participants, their level of commitment, and the visibility of the event.
A radioactive element has a half-life of 3000 years. If a sample of this element begins with a mass of 60 grams how long would you have to wait for the mass to decrease to 15 grams?
You would have to wait 6,000 years for this to occur, because it requires twice the half-life to reduce the radioactive isotope to 1/4 of its original mass.
What is the amount of radioactive material needed to sustain a chain reaction in order to provide useful energy called?
The critical mass.
What is the amount of radioactive material needed to sustain a chain reaction in order to provide useful energy?
The critical mass.
Minimum mass of material requied for the nuclear chain reaction to occur in a nuclear bomb is called?
The critical mass
What is subcritical mass?
Subcritical mass refers to an amount of fissile material that is not enough to sustain a nuclear chain reaction. This means the material does not reach a critical mass where nuclear fission reactions can continue in a self-sustaining manner. In order for a sustained chain reaction to occur, the material must exceed the critical mass threshold.
What causes radioactive explosions?
An uncontrolled neutron chain reaction in a supercritical mass of fissile material.Very high temperature and pressure, enough to ignite thermonuclear fusion in fusion fuel.
What is the amount of fissionable material required to continue a reaction at a constant rate?
The amount of fissionable material required to sustain a nuclear reaction at a constant rate is determined by the material's critical mass. The critical mass is the minimum amount of fissionable material needed to sustain a chain reaction, and it varies depending on the material and the reactor design. By controlling factors such as neutron moderation and absorption, reactor operators can adjust the critical mass to maintain a steady reaction rate.
How is the atom bomb constructed to ensure that it does not go off immediately?
The radioactive material in the bomb is kept apart and are less than the critical mass until they collide into each other. EGHS Ftl
Does critical mass depend on polarity?
No, critical mass does not depend on polarity. Critical mass is simply the amount of fissile material needed to sustain a nuclear chain reaction. Polarity, which is a property of molecules, does not play a role in determining critical mass.
One thing that is not a factor in determining critical mass is?
the age of the material
Critical mass is the of material required to produce a chain reaction?
minimum amount
What is the quantity of fissionable material called that CANNOT sustain a nuclear reaction?
Subcritical mass is the quantity of fissionable material that cannot sustain a nuclear reaction. When the amount of fissionable material is below the critical mass required to sustain a chain reaction, it is considered subcritical.
The smallest amount of a fissionable material that will give a self-sustaining chain reactions is called the?
The smallest amount of a fissionable material that will produce a self-sustaining chain reaction is called the critical mass. This mass of affected by geometry and other factors such as temperature, pressure, and moderator.
