Question

CA state regulations expressly state: " The intensity of the x-ray beam at the tabletop of a fluoroscope should not exceed _ of tube current when operating at 80 kVp"

1. 3.0 rads/min for each mA
2. 3.0 rads/hr for each mA
3. 2.2 rads/min for each mA
4. 2.2 rads/hr for each mA

Answer 1

California state regulations set safety limits for the intensity of x-ray beams in medical diagnostics.

The regulation limits the amount of radiation, measured in rads, that a patient can be exposed to per milliampere of tube current when a fluoroscope operates at 80 kVp.

Step-by-step explanation:

The intensity of the x-ray beam at the tabletop of a fluoroscope, according to California state regulations, should not exceed a certain limit of radiation per milliampere of tube current when operating at 80 kVp. This is to ensure patient safety by limiting the exposure to x-rays during diagnostic procedures.

Medical doses of radiation are carefully controlled and diagnostic doses are kept as low as reasonably achievable, balancing the risks and benefits of the exposure.

The intensity, measured in 'rads', is a unit of absorbed radiation dose, indicating the amount of energy deposited in tissue. Modern fluoroscopy equipment and techniques aim to minimize patient exposure while still providing adequate imaging quality for diagnosis.
