Efficiency of bremsstrahlung production
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.

WebHowever, because of the low efficiency of bremsstrahlung production and because of the considerable self absorption of the produced bremsstrahlung radiation in high-Z body of the bremsstrahl ung target, this target must effectively be cooled down by distilled water under pressure. WebAs usual collimators used for scintigraphy have an efficiency of 100 cps/MBq, even for high-energy beta-emitting isotopes, the total efficiency of Bremsstrahlung imaging is never more than 20 cps/MBq. For a lower-energy tracer, such as 14 C, the yield is at least 100-fold weaker and therefore not suitable.
