To Shield or Not to Shield: Application of Bismuth Breast Shields
American Journal of Roentgenology, 2013The purposes of this essay are to describe the effects of bismuth breast shielding on radiation exposure of the breast and posterior chest wall and to present arguments for and against the use of breast shields.Breast tissue may receive substantial radiation doses during CT examinations. Bismuth shields effectively reduce breast exposure at the expense

Shielding effectiveness measurements for ferromagnetic shields
2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007, 2007This paper proposes a new way to measure the shielding effectiveness of ferromagnetic shields. The procedure combines an experimental characterization of the shielding material to a forthcoming numeric simulation. Magnetic hysteresis is reduced to a series of equivalent B-H linear relations through an optimization procedure applied to a measured set of

Shielding Effectiveness Measurements for Ferromagnetic Shields
IEEE Transactions on Instrumentation and Measurement, 2009This paper proposes a new way to measure the shielding effectiveness of ferromagnetic shields. The procedure combines an experimental characterization of the shielding material and numerical simulations. In a first case, magnetic hysteresis is reduced to a series of equivalent B -H linear relations through an optimization procedure that is applied to a

A secondary gonadal shield for use in the pelvic irradiation of males was designed and built using material and apparatus available with the Cerrobend blocking system. The gonadal dose was reduced to approximately 1.5 to 2.5% of the given dose.

AS compared to transmission lines, it is more important that overhead ground wires or vertical masts over substations be correctly located so as to provide shielding of the structure against direct strokes of lightning. In a previously published paper1 the authors discussed the shielding characteristics required for transmission lines.

The amount of radiation delivered to the testes in x-ray examinations must be kept as small as possible, consistent with the clinical needs of the patient. Important means of accomplishing this are the elimination of unnecessary examinations and careful coning of the x-ray beam; but, even when coning is carefully done, the testes receive a relatively ...

Shielding Effectiveness Theory of Shielding
2019The hypothesis upon which the present accepted theory of shielding consisting of the equation SE = R + A + B is based is presented. The hypothesis is based on wave theory and the analogy between transmission lines and the penetration of a wave through a barrier. A detailed analysis, comparing the value of the current delivered to a load impedance using
