What is the function of the protective housing of an x-ray tube?
The housing serves to protect the x-ray tube by serving as an electrical insulator and thermal cushion. The radiographer should take care not to touch it after long “on times” and not to use the high-voltage cables as “handles” for maneuvering the tube.
What is a diagnostic x-ray tube?
30.2 Introduction. The rotating anode X-ray tube is the most common type of X-ray tube found in diagnostic imaging departments. The heat deposited in the anode during an X-ray exposure is spread over a larger area and so there is a smaller temperature rise at the anode surface.
What is protective housing?
Protective housing means any panel, partition, dividing wall, or similar device which prevents human access to laser or collateral radiation in excess of the prescribed accessible emission limit.
What is used in shielding of X-ray?
Lead
Lead is the most widely used shielding material, because its ability to efficiently shield X-rays is superior to that of other materials owing to its high Z number, high density, and low cost.
What is X-ray tube housing made of?
To provide the radiological protection, this tube housing is made of 1/8″ steel, except for the square window through which the X-ray beam would be directed.
What is tube housing in radiology?
The x-ray tube housing is a cover for x-ray tubes to prevent leakage radiation to exceed specified limits. The electrons collide with the anode and this deceleration generates x-rays (bremsstrahlung). The high vacuum allows the electron beam an unimpeded passage.
Is there anything radioactive within the diagnostic X-ray tube?
X-rays are produced within the X-ray machine, also known as an X-ray tube. No external radioactive material is involved. Radiographers can change the current and voltage settings on the X-ray machine in order to manipulate the properties of the X-ray beam produced.
What is the most common cause of tube failure?
A common failure for relatively long lived tubes is arcing. The most common proven causes of arcing are: high residual gas pressure, degradation of insulators and spurious electron emission (commonly called “field emission”). The first two subjects were touched on earlier.

What are the 4 factors that determine radiation shielding requirements?
There are various lead shielding considerations including radiation type, equipment orientation, workload and occupancy but exposure time and distance are the most important in calculating the level of protection required for your application.
Is patient shielding necessary?
Medical experts have recently concluded that patient shielding during diagnostic medical imaging, a common practice for more than 70 years, is no longer necessary. In the 1950s, doctors began to shield reproductive glands and a pregnant woman’s fetus during medical imaging.
