A digital autoradiography system based on double sided silicon strip d
etectors (1.6x1.6 mm(2) active surface with 100 mu m pitch) has been d
eveloped and successfully tested with beta-emitting tracers. It is sho
wn here that the system is able to perform imaging of organic material
with specific sensitivity as small as 0.002nCi/mm(2), and to record a
ctivity measurements with good linearity in the range 0.002-20 nCi/mm(
2). Autoradiographic images of clusters of mammary cells marked with o
rtho-(P-32)phosphate, obtained with an exposure time of about 10 min a
re presented.
