CAMRT Radiography Practice Exam

Which property of Tungsten contributes to heat dissipation?

1. High melting point

2. High thermal conductivity

3. High atomic number

4. Low pitting and cracking

The correct answer is: High thermal conductivity

The ability of a material to dissipate heat effectively is significantly influenced by its thermal conductivity. Tungsten possesses high thermal conductivity, which allows it to efficiently transfer heat away from areas where it is generated, such as in the anode of an X-ray tube during radiographic procedures. This property is crucial because it helps to prevent overheating and prolongs the life of the equipment. High thermal conductivity ensures that heat does not accumulate, thereby maintaining optimal operating conditions. While other properties such as a high melting point contribute to the overall stability of tungsten in high-temperature environments, it is the high thermal conductivity that specifically addresses effective heat dissipation.
