ANTIBIOTIC SUSCEPTIBILITY TESTING. Bacteria demonstrate two kinds of resistance to antibiotics, namely intrinsic resistance and acquired resistance. Intrinsic resistance means that the species was resistant to an antibiotic even before its introduction.
Radioactive contamination and radiation exposure could occur if radioactive materials are released into the environment as the result of an accident, an event in nature, or an act of terrorism. Such a release could expose people and contaminate their surroundings and personal property.
Example of Radiant Energy. Physics: The term radiation refers to the process of release of electromagnetic energies in the form of radiant energy. Common usage: Radiation, unless qualified by context, refers to any process of spreading out from a source.
