In the present, external environmental factors affect human health. In particular, the most important issue is fine dust in these days. Because fine dust is inhaled through the human respiratory system is known to be harmful to health. Tunnels for cars and people can also be easily seen around us. This study, the amount of scattering radiation was measured for walkable tunnels about dust. For the measurement method, dust and radiation dose in the tunnel were measured on good weather (fine dust level: 0~30 μg/m3) and normal day (fine dust level: 0~80 μg/m3). The measurement resulted in an increase of 10~20% of dust in the center of the tunnel on a good weather day and an increase of 20~30% of dust in the center of the tunnel on normal weather. On the other hand, the results of tunnel measurement of radiation dose increased by 10~20% at the center of the tunnel non-depending on the weather. In conclusion, you should pay attention to dust and scattering radiation while walking in the tunnel and be sure to wear respiratory protection when working inside the tunnel for a long time.
