N. Segovia et al., RADON CONCENTRATION LEVELS IN DWELLINGS AND MINE ATMOSPHERES IN MEXICO, Nuclear tracks & radiation measurements, 22(1-4), 1993, pp. 445-448
Atmospheric radon surveys have been conducted in dwellings and mine at
mospheres from the city of Zacatecas and single family homes in Mexico
City. The monitoring was performed with track detectors, LR115 type I
I. The radon concentration values in most of the atmospheres studied w
ere less than 150 Bq/m3; the maximum value at the top soil in mines re
ached 1200 Bq/m3.
