摘要：
A method of estimating the strength of a wooden support wherein gamma rays (4) are transmitted and detected parallel to a neutral axis (5) through a cross section of the support. It also includes a method of locating regions of unsound wood in a wooden support using detection of transmitted gamma rays (4), as well as apparatus suitable for conducting both methods.
