The form of the transmission factor for sample geometries encountered in X‐ray and neutron fibre diffraction studies is considered. Transmission factors obtained by Monte Carlo experiments and a simple first‐order approximation are compared and agree to within 1% for studies of the distribution of water and cations around DNA. The first‐order approximation has the advantage of being simple and less computationally expensive.
