On the laboratory use of X-rays in timber decay evaluations

IRG/WP 2144

J D Thornton, J W Creffield, O Collett

The paper reports the results of laboratory experiments on the X-raying of some Pinus radiata sapwood blocks infected with Serpula lacrymans to determine the effect of density and moisture content on the absorption of X-rays by wood. It is concluded that with increasing moisture content there is a very marked increase in time required to pass a constant quantity of X-rays through a test block and the interpretation of X-ray data taken at unknown moisture contents may be questionable.
