❚ Indoor Air Quality Measurement
■ Targeted Facilities
The constructor must submit the measurement results of the newly built apartment complex to the mayor, county governor, or district head no later than 7 days before residents move in.
The constructor of a newly built apartment complex must measure the indoor air quality of the apartment complex for which construction has been completed and must announce it so that residents can clearly see it in the following places for 60 days from 7 days before residents move in.
1. Bulletin board at the entrance of the apartment complex management office
2. Bulletin board at the entrance to each apartment building
3. Constructor’s Internet homepage
| Type | Sample collection household | Scale |
| apartment | using with more than 5 floors used as housing | Over 100 households |
| townhouse | The total floor area of one building used as a residence exceeds 660㎡ | |
| Houses of 4 stories or less | ||
| dormitory | Used for students or employees at schools or factories, etc. | |
| Structure for communal cooking, etc. | ||
| Not in the form of an independent residence. |
■ Number of households for which test samples were collected
The number of households sampled in a newly built apartment complex is based on three households (low-rise, mid-rise, and high-rise) when the total number of households in the apartment is 100.
One generation is added for every 100 generations, and samples are collected up to 20 generations.
(Radon measurement can be conducted up to 12 households) At this time, it increases in the order of mid-rise, low-rise, and high-rise.
| 100~199 | Sample collection household |
| 100 ~199 | 3rd generation |
| 200 ~ 299 | 4th generation |
| 300 ~ 399 | 5th generation |
■ Measurement standards and test methods (applied from July 1, 2019)
| Type | Sample collection household | volatile organic compounds | Radon (Bq/㎥) | ||||

| Recommended standards | 210 or less | 30 | 1000 | 360 | 700 | 300 | 148 |
| measurement method | Collected by adsorption onto DNPH Tenax tube using a collector (Measure twice for 30 minutes at a flow rate of 200 to 1000 mL/min) | Collected by adsorbing onto Tenax tube using a collector (Measure twice for 30 minutes at a flow rate of 50 to 200 mL/min) | Short-term
measurement with
a collector (3 days) | ||||
| Analysis method | HPLC method | GC/MS method | Radon continuous measurement method |
