Complications of cholecystitis and/or biliary colic may also include cholangitis, sepsis, pancreatitis, hepatitis, and choledocholithiasis (10%). In addition, Gallbladder perforation occurs in 10% of patients with cholecystitis. When perforation is localized, it may be seen as pericholecystic fluid by ultrasonography.
Half-life is defined as the time it takes for one half of a radioactive element to decay into a daughter isotope. As radioactive isotopes of elements decay, they lose their radio activity and become a brand new element known as a daughter isotope.
All isotopes of berkelium are radioactive. The most stable is berkelium-247. It has a half life of 1,380 years. Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the eLement. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. A radioactive isotope is one that breaks apart and gives off some form of radiation. Berkelium-247 has a half life of 1,380 years. The half life of a radioactive element is the time it takes for half of a sample of the element to break down. After 1,380 years, only half of a 10-gram sample (5 grams) of berkelium-247 would be left. The other half would have changed into a different element.
