Study of variance and covariance terms in linear attenuation coefficient measurements of irregular samples through the two media method by gamma-ray transmission

Measurements of linear attenuation coefficients of irregular shaped samples by two media method

“…(4)) is a function of different variables namely l 1 , l 2 , C 1 and C 2 . The resultant uncertainty in the measurement of linear attenuation coefficient due to the uncertainties in measurements of each independent variable l 1 , l 2 , C 1 and C 2 is given by the following relation, as stated in [22] l AE ffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffi ffi…”

“…five materials instead of four) to obtain more independent repetitions for the linear attenuation value of sample under study. Kuramoto and Appoloni [22] studied the propagation of errors in the measurements of linear attenuation coefficients using two media method.…”
