WebTungsten is required as it has a high atomic number to improve the efficiency of bremsstrahlung x-ray production (see below), and a high melting point. There is a good deal of heat generated and hence the need for high melting points and the copper anode is able to conduct heat away effectively. WebJan 1, 1983 · The results show that at $1.25 per curie, 60Co gammas appear to offer no cost advantage over the bremsstrahlung beam. Even at 0.75 $/Ci of 60Co, radiation processing with a dual mode electron accelerator is cost competitive if 50% of the annual volume is treated with electrons.
