For medical purposes , X-ray filters are used to selectively attenuate , or block out , low - energy rays during x-ray imaging ( radiography ) . Low energy x-rays ( less than 30 keV ) contribute little to the resultant image as they are heavily absorbed by the patient 's soft tissues ( particularly the skin ) . Additionally , this absorption adds to the risk of stochastic ( e.g. cancer ) or non stochastic radiation effects ( e.g. tissue reactions ) in the patient . Thus , it is favorable to remove these low energy X-rays from the incident light beam . X-ray filtration may be inherent due to the X-ray tube and housing material itself or added from additional sheets of filter material . The minimum filtration used is usually 2.5 mm aluminium ( Al ) equivalent , although there is an increasing trend to use greater filtration . Manufacturers of modern fluoroscopy equipment utilize a system of adding a variable thickness of copper ( Cu ) filtration according to patient thickness . This typically ranges from 0.1 to 0.9 mm Cu .

Brown v. Board of Education of Topeka , 347 U.S. 483 ( 1954 ) , was a landmark United States Supreme Court case in which the Court declared state laws establishing separate public schools for black and white students to be unconstitutional . The decision effectively overturned the Plessy v. Ferguson decision of 1896 , which allowed state - sponsored segregation , insofar as it applied to public education . Handed down on May 17 , 1954 , the Warren Court 's unanimous ( 9 -- 0 ) decision stated that `` separate educational facilities are inherently unequal . '' As a result , de jure racial segregation was ruled a violation of the Equal Protection Clause of the Fourteenth Amendment of the United States Constitution . This ruling paved the way for integration and was a major victory of the Civil Rights Movement , and a model for many future impact litigation cases . However , the decision 's fourteen pages did not spell out any sort of method for ending racial segregation in schools , and the Court 's second decision in Brown II ( 349 U.S. 294 ( 1955 ) ) only ordered states to desegregate `` with all deliberate speed '' .
