Visual inspection
Environmental inspection
Performance testing
Visual inspection is governed by:
SC35
T/F
Discolouration of outside cables may be an indication of internal heat
True
What does performance testing do?
Evaluates the performance of the xray generator and xray tube with specialized test instruments
Measures the charge from the number of ion pairs created within a gas caused by incident radiation
Used with voltages of 100-300V
Ion chambers
(Least sensitive, most common)
Used with voltages of 300-900V
Measure the charge from the number of ion pairs created within a gas caused by incident radiation
Proportional counter
Used with voltage of 900-1200V
Greatest sensitivity
Geiger-Muller counter
KERMA
Kinetic energy released in matter
