Geiger Mueller region		"attraction" of the electrode that cause secondary emission each time a dynode is struck
Gas detector		device that detects photons; NaI(TI), Ge(Li), Si(Li) are examples
recombination		involves more than one circuit; enables simultaneous or sequential counting of radioactivity
Cutie Pie		worn by radiologic personnel for personal radiaiton monitoring
ionization		converts light energy into electrical energy
film badge		used to detect biological samples
dose rate meters		increase voltage leads to this region
probe		electronic device that accepts singlr pulses from a radiation detector and counts them
proportional region		above saturation voltage; seen ion pairs--invloves gas amplification
scintillation detectors		no pulse height, a plateau is reached; saturation
continuousregion		used in the method of counting thyroid uptake
Preamplifier		example of a portable dose rate meter
ionization chamber		involves ion pairs collected on the walls of an ion chamber
crystal		pulse height shows no difference as to primary events
Pulse Height Analyzer		most widely used detector
dead time		used to measure radiation in the ionization region
photomultiplier		accepts certain pulses and rejects others
TLD		surpasse the G-M region and is infinity
High-voltage		thermoluminescent dosimetry
scaler		amplifies voltage
well counter		if it's not alive; counter cannot respond to another ionizing event
gain control		portable; enclosed volume of gas for detection
Multichannel analyzers		allows increase or decrease amplification
