Techniques for producing X-ray negatives of dendrochronological specimens have been developed at the Geological Survey of Canada and the Nondestructive Testing Laboratory, Mines Branch, The radiographs are produced to provide tree-ring density data to supplement ring-width measurements for dating and climatic studies. New specimen preparation techniques and X-ray methods are discussed. The quality and quantity of tree-ring information is enhanced by the use of X-ray analysis.
