Zt. Sun et al., RADON DISTRIBUTION MEASUREMENT OF LUGO COALMINE BY CSR TRACK DETECTION, Nuclear tracks & radiation measurements, 22(1-4), 1993, pp. 461-462
We discuss the relationship between the Alpha radioactivity derived fr
om Uranium and Thorium natural radioactive systems, especially from Ra
don and the safe production in coalmine region. The Alpha radioactive
distributions of different sites were detected and measured by using C
SR technique in Lugo Coalmine. Measurement shows that the radon densit
y distributions under the ground is less than that on the ground under
today's productive condition in a large area in Henan Lugo coalmine.
