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.
BRAIN: Nerve cells (neurons) and brain blood vessels can die, leading to seizures. EYES: Radiation exposure increases the risk of cataracts. THYROID: When a nuclear reactor malfunctions, radioactive iodine (I-131) can be released into the atmosphere (this is one of the particles that hangs out in a radioactive plume).
