Calculation of ß filter thickness and transmission
Part of the Philips Technical Library book series (PTL)
A Ni filter has been constructed in such a way that only 2% of the incident Cu Kβ radiation may pass. Given that the density of Ni is 8.92 g/cm3 and that the mass absorption of Ni for Cu Kα and Cu Kβ is 49.2 cm2/g and 286 cm2/g respectively. calculate:
The thickness of the filter
The percentage of incident Cu Kα radiation that can pass the filter.
