Bone mineral content of the forearm in a healthy population. 1977

P Karjalainen, and E M Alhava

The bone mineral content in the distal radius, in the midshaft radius and ulna was measured in 83 healthy males and 89 females from 11 to 87 years old using the 241Am gamma ray attenuation method. The age distributions of different 'density' quantities characterizing bone mineral are presented and the usefulness of these quantities is discussed.

D005720	Gamma Rays	Penetrating, high-energy electromagnetic radiation emitted from atomic nuclei during NUCLEAR DECAY. The range of wavelengths of emitted radiation is between 0.1 - 100 pm which overlaps the shorter, more energetic hard X-RAYS wavelengths. The distinction between gamma rays and X-rays is based on their radiation source.
