In order to provide scientific basis for compiling the data of a Reference Chinese Man, skeleton specimens from 486 adults (409 males and 77 females, 20-60 years old) from southern and northern regions of China were collected. By measuring the dry weights for all the eighteen kinds of bone and using the specific values of wet and dry bone weights from external information, the reference values of mass of total skeleton for Chinese adults (8.0 kg for males and 5.5 kg for females) were first proposed. There are apparent differences not only between males and females but also among various geographic locations. The relative weights of different kinds of bone as percentages of body weight for Chinese adults were suggested simultaneously. From this the mass of total skeleton and of different kinds of bone can be calculated directly according to the actual body weight of individuals. In addition, on the basis of the mass of source organs and target organs in bones from ICRP Reference Man, the relevant values for Chinese adults can be derived respectively. The data are most significant in the calculation of bone dose in the field of radiation protection.
