In this study the level of 222Rn concentration at 35 positions in air of the big ancient

famous bazaar (Qaysery Naqeeb) which contains 110 shops and located in the center of

Sulaimani city have been assessed. During the winter and summer seasons of 2014, 222Rn

concentrations have been measured by using (CR-39) solid state nuclear detector. In

winter, the maximum and minimum values of 222Rn concentration were

(206.901±10.958) Bq/mᵌ and (44.978±5.109) Bq/mᵌ respectively, with an average value

of (132.849± 8.780)Bq/mᵌ; while in summer the maximum and minimum values of 222Rn

concentrations were (255.476± 25.809) Bq/mᵌ and (99.852± 6.306) Bq/mᵌ ,respectively,

with an average value of (158.215± 12.578)Bq/mᵌ, this difference reveals the role of

higher temperature and humidity rates in the variation of radon concentrations were high

radon concentrations corresponds to high temperature and low humidity rates. In several

positions the obtained values were nearly within the acceptable range of radon level

recommended by the International Commission on Radiological Protection and the limit

recommended by World Health Organization (WHO), but in the most other positions

these limits were exceeded due to the structures of material building and lack of

ventilation. The effect of temperature on radon concentration was also observed.
