Recycled aluminium used in low cost shielding

The used high atomic weight and density materials, like lead and barite, contribute with the environmental problem, when they will be hand and disposal. Therefore we showed the recycled aluminiumis possible as shielding material for mammography X ray. In addition to the environmental gain, we will have the social gain, since the aluminium used came from recycled. Attenuation measurements could made with recycled and high pure aluminium (99.999%), the results shows better than 1%.
