Radioactive Airborne Species Formed in the Air in High Energy Accelerator Tunnels
The particle size distributions of radioactive nuclides formed in accelerator beam line tunnels were measured by using a diffusion battery and were found to be log-normal with a geometric mean radius of about 28 nm. The radioactive aerosol formation was well explained by a simple physical adsorption of radioactive nuclides to the ambient non-radioactive aerosols. The fractions of aerosol and gaseous components were measured for individual nuclides formed in the air of a high-energy accelerator tunnel. The formation of these <SUP>11</SUP>C and <SUP>13</SUP>N species was explained by their hot-atom reactions and subsequent chemical reactions.
