Abstract :Relaxation lengths and half-thickness values of different types of wood were determined using gamma radiation from 60C0 source. Results show that oxystigma insert ignore into journalissuearticles values(Oxystima spp); has the highest relaxation length of 23.810cm, while mangrove insert ignore into journalissuearticles values(Rhizoohora spp); has the least relaxation length of 1.247 cm. Results also show that Oxystima insert ignore into journalissuearticles values(Oxystima spp); has the highest half thickness value of 16.500 cm and Mangrove insert ignore into journalissuearticles values(Rhizophora spp); has the least half-thickness value of 0.864 cm. Two mathematical models have been developed for the prediction or determination of density r, variation with relaxation length and half thickness value of wood. A good agreement insert ignore into journalissuearticles values(greater than 80% in most cases); was observed between the measured values and the predicted ones insert ignore into journalissuearticles values(models 1 and 2);.
