The results of a methodical ten-year-long, case-controlled study of residential radon exposure in Worcester County, Massachusetts, found an apparent 60% reduction in lung cancer risk amongst people exposed to low levels (0–150 Bq/m 3) of radon gas; levels typically encountered in 90% of American homes—an apparent support for the idea of ...
Radon is measured in picocuries per liter of air (pCi/L) or becquerel per cubic meter (Bq m-3). Both are measurements of radioactivity. The World Health Organization (WHO) sets the ideal indoor radon levels at 100 Bq/m-3. [97] In the United States, it is recommend to fix homes with radon levels at or above 4 pCi/L.
The maximum tpma (out) must be under 33.5 degrees Celsius and indoor temperature of 31% of the tpma (out) plus 21.3 degrees Celsius. For example, the tpma (out) 33.5 degrees Celsius, the indoor temperature shall not be over 31.7 degrees Celsius. If tpma (out) is over than 33.5 degrees Celsius then a mechanically conditioned space would be in place.
§ 153-158 Act of (in German) The new radon protection regulations for workplaces and new residential buildings have been binding since January 2019. Extensive radon contamination and radon precautionary areas have been determined by the ministries of the environment of the federal states (as of June 15, 2021).
And — more importantly for Pittsburgh (9-3) — the team is keeping pace in the AFC. Russell Wilson completed 8 of 9 passes over 10 air yards for 205 yards and 2 TDs (+34.8% CPOE, his 3rd ...
For example, in the United States, people with a high school degree had 6.2% higher estimated exposure to PM 2.5 compared to those with a college degree. In addition to PM 2.5, people with a high school degree or lower are estimated to have at least 10% more exposure to Al, Ca, Cl, EC, SI, TI, V, and Zn when compared to people with a college ...
Radon is thus assumed to be the second leading cause of lung cancer after smoking, and accounts for 15,000 to 22,000 cancer deaths per year in the US alone. [9] [better source needed] However, the discussion about the opposite experimental results is still going on. [10] About 100,000 Bq/m 3 of radon was found in Stanley Watras's basement in 1984.
A 2.5% increase is below the average COLA since it became annual in 1975, but it could also be worse. There have been a few instances when benefits remained the same, but that's more of an anomaly ...
