Nuclear energy can also be released by fusion of two light elements (elements with low atomic numbers). The power that fuels the sun and the stars is nuclear fusion.In a hydrogen bomb, two isotopes of hydrogen, deuterium and tritium are fused to form a nucleus of helium and a neutron. This fusion releases 17.6 MeV of energy.Unlike nuclear fission, there is no limit on the amount of the fusion that can occur.uclear energy can also be released by fusion of two light elements (elements with low atomic numbers). The power that fuels the sun and the stars is nuclear fusion.
Definition. High white blood cell count is an increase in disease-fighting cells (leukocytes) circulating in your blood. High white blood cell count is also called leukocytosis. The threshold for high white blood cell count varies from one medical practice to another.
The threshold for a low white blood cell count varies from one medical practice to another. Some healthy people have white cell counts that are lower than what's considered normal. A count lower than 4,000 white blood cells per microliter of blood is generally considered a low white blood cell count.
