“Hot” or radioactive particle in lung tissue”
photo by Del Tredici, Burdens of Proof by Tim Connor, Energy Research Foundation (1997)
This is a photo of a “hot particle”, in this case a 1 micron particle of plutonium,
and shows the alpha tracks emitted from that particle in one year.
Plutonium in Lung Tissue: The dark, star-like image in this photograph (magnified 500 times) shows tracks from alpha particles radiating front a speck of plutonium lodged in the lung tissue of an ape. Alpha radiation from plutonium and other alpha-emitting radionuclides can be blocked by skin or even a piece of paper but it is the most biologically destructive form of ionizing radiation when the alpha-emitting substance is deposited in the soft tissue of internal organs like the lung. The alpha tracks shown above were captured over a two-day period. Lawrence Radiation Laboratory, Berkeley California, September 1982.
