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.
Nuclear power plants do not normally give off radiation that can be detected, but then can have accidental leaks of radioactive materials which, in turn give off radiation. Th â¦ ese can get into the environment and be dispersed, eventually causing damage.ince there is no  benefit from radiation, no amount of increase in exposure to  radiation is good. Nevertheless, there are things we cannot do  without exposure to radiation, such as getting dental X-rays or  consuming the amount of potassium we need every day.
