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.
The nucleus is surrounded by electrons. The half-life of a radioactive isotope is the time taken for half its radioactive atoms to decay. There are three main types of radiation, called alpha, beta and gamma radiation, which all have different properties.Radiation can damage cells and make them cancerous.ll the atoms of a given element have the same number of protons and electrons. However, the number of neutrons can vary. Atoms of the same element that have different numbers of neutrons are called isotopes of that element.
