A student attempts to determine the linear absorption coefficient \mu of an X-ray absorber. The incident radiation at the surface is 64\text{ counts per second} and the transmitted radiation after passing through 4\text{ mm} of the sample material is 4\text{ counts/s}. What is the value of \mu?
- (A)
8\text{ m}^{-1} - (B)
128\text{ m}^{-1} - (C)
693\text{ m}^{-1} - (D)
800\text{ m}^{-1}
