A photographic emulsion impregnated with a radio active thorium salt reveals the tracks of alpha particles when developed As Ernest Rutherford Frederick Soddy found in the decay of thorium initiates a chain of decays First one radioactive element is formed then that decays to another so on This is why the emulsion picture shows the tracks of two or more alpha particles emerging from the same spot they are the result of successive stages in the decay of a single nucleus The length of the alpha tracks in this negative picture is about mm
This giclée print delivers a vivid image with maximum color accuracy and exceptional resolution. The standard for museums and galleries around the world, giclée is a printing process where millions of ink droplets are “sprayed” onto high-quality paper. With the great degree of detail and smooth transitions of color gradients, giclée prints appear much more realistic than other reproduction prints. The high-quality paper (235 gsm) is acid free with a smooth surface.
