Recent reports indicate the decline of BMD in young age bracket and plead special needs to promote BMD of the youth. As BMD examination is thought to spread in young people, absorbed dose of these clients will become a serious problem. Absorbed dose of BMD examination with several different dual energy X-ray absorptiometry (DEXA) apparatus was measured and compared using a same measuring method. Measuring method employed in this study is easy and useful to measure absorbed dose of BMD examination using DEXA.
