Abstract: An exact solution is presented for the solid angle subtended by a circular detector for a linear source. It is based on Conway's equation for a non-coaxial point source, involving an integral of Bessel functions (Conway, 2006). Some numerical examples are calculated and compared with the results obtained with a recently published closed formula (Galiano and Pagnutti, 2006), which is incorrect but can be improved by applying a correction factor.
