Technical Problems on X-ray Television Apparatus

Dosimetry of Occupational Radiation around Panoramic X-ray Apparatus

Background: Panoramic imaging is one of the most common imaging methods in dentistry. Regarding the side-effects of ionizing radiation, it is necessary to survey different aspects and details of panoramic imaging. In this study, we compared the absorbed x-ray dose around two panoramic x-ray units: PM 2002 CC Proline (Planmeca, Helsinki, Finland) and Cranex Tome (Soredex, Helsinki, Finland).<br ...

Dosimetry of the Very Weak X-radiation Generated in Television Receivers and X-ray Diffraction Apparatus

With many kinds of apparatus in which electron tubes are operated at high voltages, the possiblepresence of very weak, soft Xvradiation, (i.e. Xradiation of low penetrating power) in the neighbourhood must be given due consideration. The question arises in such apparatus as X-ray diffraction equipment, formerly found only in research laboratories but now widely used industrially in inspection a...

X-ray pulse apparatus based on explosive electron emission

One of the basic problems of the design of the portable x-ray devices for the works under the field conditions is to get smallest possible weight and the overall sizes. The classical apparatuses, which contain thermo-emission X-ray tube and source of constant high voltage as a rule have weight about 15-30 kg, which strongly impedes their use in the nonstationary conditions. In the proposed work...
