This chapter focuses on the autoradiographic methods used for electron
microscopy. The isotope of choice is tritium. It is the most easily adapted
isotope because of its low average energy and consequently its high specific
ionization. 3H emits a β-particle of 18 keV maximum energy and, therefore, gives
excellent resolution and sensitivity. The nuclear emulsions used for
autoradiography are compos... hiện toàn bộ
