To Shield or Not to Shield: Application of Bismuth Breast Shields

American Journal of Roentgenology, 2013
The 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, 2007
This 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
