85Kr have been used for estimating ventilation rates in rooms. This paper presents a method to evaluate the ventilation rate using radon daughter aerosol normally present in a room as a tracer. By using solid-state nuclear track detectors (SSNTD), radon and its progeny levels are determined. For a steady-state level of radon and its daughter concentrations, the ratio of working level (WL) to radon is estimated. This ratio is related to the pseudo -ventilation rate which is the sum of actual ventilation rate and plate-out rate as follows:
WL=
f
a
×10
-5(2.8+14
f
b
·
f
c
)
C
Rn
The actual ventilation rate is obtained by subtracting the plate -out rates of attached and unattached fractions of radon daughters from the pseudo-ventilation rate. The results of the measurements carried out in 18 different types of houses in Bombay are presented. |
