VitaTech performed the EMI/RFI ambient site survey in August of 2003 and the first building EMI/RFI assessment by October 2004 for the Center for Functional Nanomaterials (CFN) at Brookhaven National Labs in Upton, New York. Magnetic shielding was recommended for the main switchgear room, conduit risers besides selected transformers and electric panels. In May of 2006, VitaTech was contacted by E.W. Howell Co., Inc. for a quote to install, test and certify an AC ELF (extremely low frequency) magnetic shielding system for the main switchgear room, conduit risers and supplemental transformer and electric panel shields. VitaTech commenced work in June 2006 and successfully completed the shielding project in late August 2006. The final site survey was performed in 2007 for the commissioning of the research facility.
It was necessary to shield the main switchgear room and conduit risers located on first floor of the Center for Functional Nanomaterials (CFN) to minimize the impact in nearby adjacent research laboratories designated for nanotechnology, electron microscopy, magnetic resonance imaging and other scientific tools from elevated to high AC extremely low frequency (ELF) magnetic field emissions that could comprome the optimum tool performance. Furthermore, transformer and electric panel shields were installed around selected electric panels adjacent to EMI sensitive laboratories.
