However, as lung cancer is the most common cancer worldwide, even a small benefit would be useful, and a trial of chest X-rays large enough to detect a 10% reduction in mortality (which would have been missed on previous studies), is now ongoing in the US [ 37].
However, the inspection of heavy materials or thick objects requires X-ray energies larger than the maximum energy provided by commercial X-ray tubes (600 kV).

In the p53-knockout mouse testes, large-sized SSC lying at the basal membrane were also observed, and 10 days after a 5 Gy dose of X-rays, these large-sized spermatogonial cells increased.
Jackie's X-rays were as large as bath mats, and he washed and dried his hands before removing them from their separate envelopes and presenting them to me.
One sure way to avoid damage to film is to mail it or send it by a shipping company like FedEx or U.P.S., but first check on what security procedures the company follows and mark the package as film, with a "Do not X-ray" note in large letters.
The x-ray flare is large in extent, has fine strulctuire, and follows a neutral magnetic line.
Chest X-ray showed a large mass lateral to the left ventricle extending to the left chest wall.
This chapter covers the history of the first groups to employ single crystal x-ray diffraction of large biological molecules with the purpose of discovering a drug.
An experiment involving muonic hydrogen requires an X-ray detector having large area and working under strong magnetic fields (5 T) with good energy and timing resolution.
