Abstract

fetched live from OpenAlex

Radon, one of the pollution sources of indoor air, is colorless, odorless, and tasteless noble gas, and is easily inhaled by humans, causing them lung cancer. The purpose of this study is to examine an amount of radon emission from gypsum boards among indoor building materials, and analyze indoor radon concentration through ventilation, which is another control method. Although it is known that 80-90% of radon flows into indoors through soil, it was also identified at high-rise apartment floors. This is judged to be resulted by building materials, and among them, gypsum board is being pointed out as the main cause. The standard of radon concentration is 148Bq/㎥ in America and Korea and 200Bq/㎥ in Canada, and Sweden is applying stricter standard to new houses (200Bq/㎥) than existing houses (400Bq/㎥). There are five gypsum board plants in Korea, Daejuk, Yeochoen, Daesan, Yeosu, and Ulsan, and gypsum boards that had been produced by each plant since 2014 were collected and then an amount of radon emission of one week was examined. As a result, max. 20Bq/㎥ was recorded, which is lower than the average indoor radon concentration, 48Bq/㎥. In addition, because an amount of radon emission from gypsum board produced in 2010 was confirmed to be 215Bq/㎥, it seems that phospho-gypsum board was converted to desulfurized gypsum board only lately, being applied by QC (Quality Control). Thus, it is needed to find out ways to control radon, ventilation or remodeling, for existing buildings, although gypsum boards of recently constructed buildings could be free from radon. For a basic way to control indoor radon spreading, ventilation should be done. For the experiment, gypsum board that produces a large amount of radon was put in a self-produced acrylic vessel, and ventilation was applied by blowing wind to it using a DC fan, and the change of an amount of radon contained in the vessel was observed. When the amount of radon 168Bq/㎥ was constantly applied by ventilation (once, wind speed 0.12m/s), it was reduced down to 16Bq/㎥ 4 days later, and when the amount of radon 303Bq/㎥ was constantly applied by ventilation (three times, wind speed 0.36m/s), it was reduced down to 30Bq/㎥ 4 days later. It is judged to be a satisfactory level because it is between 15Bq/㎥, outdoor average radon concentration, and 48Bq/㎥, indoor average radon concentration.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
