Which statement is true regarding X-ray screening for tuberculosis?

The assertion that X-ray screening for tuberculosis is appropriate for miners holds merit based on their occupational exposure risk. Miners may encounter environments that facilitate the spread of respiratory diseases, including tuberculosis, due to prolonged exposure in confined spaces where ventilation is limited. This makes screening particularly relevant as it aids in identifying active cases of tuberculosis early on, which can help prevent outbreaks in this high-risk group.

Screening practices are typically guided by epidemiological considerations, and in the context of miners, there's a compelling argument for using X-ray examinations to monitor lung health and detect any signs of tuberculosis that could be exacerbated by their working conditions. Regular X-ray screenings in such populations not only contribute to timely diagnosis and treatment but also to protecting the health of others who may be at risk of exposure.

In contrast, other groups mentioned in the options either do not represent the high-risk category that miners do or have different screening recommendations based on public health guidelines, which highlights why the other statements do not hold the same accuracy regarding the relevance of X-ray screening for tuberculosis.
