Which of the following can be done to avoid loss of intensities of X-r

1.	Which of the following can be done to avoid loss of intensities of X-rays due to the absorption of long wavelength X-rays?(a) Apparatus must be contained in a chamber(b) Air in the chamber must be replaced by helium(c) Inert gas atmosphere must be provided(d) Proper slits must be usedI had been asked this question in final exam.Question is from X-Ray Fluorescent Spectrometer in portion X-Ray Spectrometers of Analytical Instrumentation
Answer» RIGHT answer is (b) Air in the CHAMBER must be replaced by helium Best EXPLANATION: Air in the chamber must be replaced by helium to avoid loss of intensities of X-rays due to the ABSORPTION of long wavelength X-rays. Vacuum chambers can also be used.
