The equivalent dose measure, which attempts to relate various forms of radiation in terms of the damage they do to living tissue, rates a neutron with an energy of less than 10keV as having a value of 5. This is compared to X-rays and gamma rays, which are both rated at 1. A thermal neutron has an energy of about 0.025 keV.
It should be pointed out that this is a very, very rough assignment of value. Also, thermal neutrons are difficult to detect, and since they are not usually tested for in such an environment as a nuclear power plant, where they are most likely to be found, there may yet be things to be learned about them.

What uranium nucleus is fissile?
The isotopes 233U and 235U are fissile with thermal neutrons and the isotope 238U is fissile with fast neutrons.
Why do biological organisms violate the law of thermal dynamics?
No biological entity violates any of the laws of thermodynamics.
The uranium 238 atom can be triggered to split when its struck by a?
By neutrons; bu the cross specific area is very small for thermal neutrons.
What make Uranium fission?
Uranium (especialy the fissile isotope) 235U is fissionable by bombardments with thermal neutrons.
How are thermal neutrons detected?
Neutrons from fission have a natural energy of about 2 Mev. In a thermal reactor these are slowed to thermal equilibrium by a moderator, at about 0.025 ev. At these lower energies (= slower speeds) we have more time to have them react with a measuring device, commonly a particle detector. Or a scintillation detector with associated light detector..
What is η?
It is the thermal regeneration factor. It is greater than one. It is ratio of neutrons generated in the fuel to the absorbed neutrons.
What uranium nucleus is fissile?
The isotopes 233U and 235U are fissile with thermal neutrons and the isotope 238U is fissile with fast neutrons.
What is fissile?
a thermal slow neutrons that will fission by a chain reaction of the nutrons.
Why do biological organisms violate the law of thermal dynamics?
No biological entity violates any of the laws of thermodynamics.
What does thermal indicates in thermal neutrons?
A thermal neutron has much less energy / velocity than a fast neutron. As a result, it has a much larger neutron absorption cross section, making it easier for it to be absorbed by certain nuclei and subsequently initiate fission. The fast neutrons that result from fission are slowed down, i.e. moderated, usually by water, in order to become thermal neutrons and to sustain the fission chain reaction.
The uranium 238 atom can be triggered to split when its struck by a?
By neutrons; bu the cross specific area is very small for thermal neutrons.
Is the detection of neutrons dependent on the energy of the neutrons?
Yes. There are different kinds of detectors for neutrons. Some are better at detecting high energy neutrons, and some are better at detecting thermal neutrons. There is no detection method that is equally good for detecting neutrons at all energy levels.
If two bodies are in thermal equilibrium in one frame will they be in thermal equilibrium in all frames?
No, if two bodies are in thermal equilibrium in one frame, they will not necessarily be in thermal equilibrium in all frames. Thermal equilibrium depends on the balance of energy exchange between the bodies, which can vary with different frames of reference due to relative motion and time dilation effects.

What is geological physical Weathering?
•Aeolian • •Biological weathering • •Exfoliation • •Thermal Expansion
What Specific organisms with biological chemical or thermal agents cause diseases?
Pathogens
Why are neutrons fired at the uranium nuclei?
Under bombardment with thermal neutrons a nuclear fission is produced with the isotopes 235U and 233U; a formidable energy is released after fission.
