Exposure to low level diagnostic radiation may be reduced by a polymeric non woven fabric in which at least one of the polymeric components contains from 15 to 50 weight% based on the weight of the component of one or more oxides or salts of an element having an atomic number greater than 49, in the absence of a coupling agent, said oxides and salts having a particle size of less than 1 micron. |
