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 ...

A study on improving shielding performance of shielded cable
Electrical Engineering in Japan, 2022AbstractWith the developments in power electronics equipment, the electromagnetic environment has become severe for electronic equipment. In the smart facility field, the stable operation of electronic devices is indispensable, and noise countermeasures must be improved.

Breast bismuth shielding in coronary CT angiography: To shield or not to shield?
Physica Medica, 2016Introduction Despite the use of bismuth shields to reduce dose to eye lens and thyroid from CT scans has been reported efficient and recommended, there are conflicting opinions regarding breast bismuth shielding during thoracic CT. Purpose To assess breast dose reduction and diagnostic quality degradation associated with the use of bismuth shields

Shielding effect of superconducting magnetically shielded room
IEEE Transactions on Magnetics, 1997A Superconducting Magnetically Shielded Room (SMSR) has been developed. Superconducting panels are soldered to form a shielding wall of which the soldered connections have normal conduction. Therefore, the Shielding Factor (SF) of the SMSR degrades especially at low frequency, which is different from a superconducting shielded room without a normal ...

Shielding of proton accelerators
Radiation Protection Dosimetry, 2011This paper discusses some of the methods that can be employed for calculating shielding of proton accelerators, showing that a simple analytical model is often useful for a first estimate before going into complex Monte Carlo simulations. In particular what we call the Monte Carlo 'hybrid' approach, which employs source terms and attenuation length ...
