After finding that both the level of radon and external gamma radiation were considerably lower within the department than in dwellings, we estimated the personal x-ray dose equivalent that can be incurred without the effective dose becoming higher than it would be at home.
We investigated whether cumulative exposure from personal diagnostic x-rays was associated with increased frequencies of chromosome translocations among radiologic technologists because they may recall past radiographic procedures better than the general public.
The average annual personal dose-equivalent Hp(10)x-rays was calculated according to Eq. 1 from the NRG readings and the local background as 0.44 ± 0.11 mSv; the maximum was 11.6 mSv.
As a consequence, working results in a lower dose than being at home as long as the x-ray-induced personal dose equivalent is lower than 1.25 mSv/year, which was the case for 131 of the 144 radiological workers, as well as for the whole group on average.
Hip fracture was confirmed by X-ray and personal interview.
One patient was TST positive, without any personal history of risk or X-ray findings of fibrotic tracts suggestive of prior infection.
Though it consistently brings such helpful novelties as wireless e-mail and canned flat-tire sealant, it never delivers the fundamental breakthroughs I pined for as a boy: time travel, X-ray vision and personal antigravity units.
A month before that, under Congressional orders, the T.S.A. removed from checkpoints the last of about 250 widely criticized Rapiscan body-scanner machines, which it had vigorously defended for years against claims that the X-ray technology invaded personal privacy.
NHS Lanarkshire lost 22 records containing personal details, assessment information and one x-ray.
The collective annual personal dose equivalent for Hp(10)x-rays was 63 mSv.
