First off, older people are at added risk for heat stroke and other heat-related illnesses, according to the U.S. National Institute on Aging. This is particularly true for those with chronic health issues, the agency cautions. Heat fatigue, heat-related dizziness, heat cramps, heat exhaustion and heat stroke are all forms of hyperthermia. The condition occurs when the body is overwhelmed by heat and is unable to control its temperature, the NIA explains.
253Es so produced was used to produce mendelevium (Element 101) by neutron bombardment. About 3 Âµg of einsteinium has been produced in the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratories by: irradiating kilogram quantities of 239Pu in a reactor for several years to produce 242Pu,
Einsteinium has a high rate of nuclear fission that results in a low critical mass for a sustained nuclear chain reaction. This mass is 9.89 kilograms for a bare sphere of 254 Es isotope, and can be lowered to 2.9 or even 2.26 kilograms, respectively, by adding a 30 centimeter thick steel or water reflector.insteinium is the element with the highest atomic number which has been observed in macroscopic quantities in its pure form, and this was the common short-lived isotope einsteinium-253.
