The purpose of calculating these values is to determine the efficiency of the filters in allowing Co K radiation to pass through and to compare the intensities of the radiation before and after passing through the filters.
The transmission factor is calculated by dividing the intensity of the Co K radiation after passing through the filter by the initial intensity of the radiation before the filter. This value is then multiplied by 100 to get a percentage.
The thickness and composition of the filter material, as well as the energy and wavelength of the Co K radiation, can affect the transmission factor. Other external factors such as temperature and pressure may also play a role.
The intensity ratio is determined by dividing the intensity of the Co K radiation after passing through the first filter by the intensity after passing through the second filter. This value can be used to compare the effectiveness of different filters in blocking or attenuating the radiation.
Calculating these values allows us to understand the effectiveness of Co K radiation filters and ensure that the appropriate filters are being used for specific experiments or applications. It also allows us to compare different filters and determine which ones are most suitable for our needs.
