... lobata, Q. kelloggii, and Q. agrifolia trees were chosen because of their age longevity, abundance, proximity to SSFL, and potential of wood to store radionuclides (Brownridge, 1984;Momoshima and Bondietti, 1994;Zhiyanski et al., 2010).

A 5 mm (.2 inch) wide increment borer was used at breast height (Speer, 2010). ...
