Abstract
Abstract Two parameters, track registration sensitivity and densitometric response in radiography with a low energy ( ∼ 4.5 MeV) proton beam and a stack of thin (100 μm) CR-39 detector foils were investigated. The optimum image quality was obtained at a layer removal thickness of about 1 μm. The image obtained under these conditions is characterized by a high track registration sensitivity (∼60%), high image contrast (the maximum value of the net optical density is ∼ 0.7) and high spatial resolution ( ∼1 μm). The application of the technique in biomedicine is illustrated by proton radiographs of botanical samples.
