Building 6580 Basement

Basenent. The Reactor Building basement has the same outside dimensions as the first floor. The floor elevation corresponds to that of the sub-pile room. The general layout is shown in.Fig. 9.2.D. 

The second product in Example 20.5, geRn, is a radioactive isotope of the gas radon. Radon-222 further decays by emitting an alpha particle. In recent years there has been concern about radon-222 that enters building basements from the soil outside. Exposure to radon gas may increase your chances of developing lung cancer, particularly if you smoke.

My active life and work were unexpectedly affected by two serious illnesses that I fought in 1979 and 1982. We spent the first two years in TA in temporary laboratories in the basement of an old science building, where I also had my office on the ground floor above the... 

I still did not have suitable low-temperature instrumentation of my own to carry out the low-temperature NMR studies, but Martin Saunders at Yale did. Thus our samples now traveled the Massachusetts Turnpike from Boston to New Haven, where with Marty we were able to study solutions of the norbornyl cation at increasingly lower temperatures using his home-built variable-temperature NMR instrumentation housed in the basement of the old Yale chemistry building. We... 

The rupture discs on some water compressors were allov/ed to discharge inside a building as the water was clean. However, by the time it had drained down through several floors to the basement of the building, it had dissolved some solid material that had been spilt on one of the intervening floors and became hazardous. Discs had failed on several occasions, for unknown reasons. Possible causes were vibration, hammer pressure, and low-cycle fatigue. 

The use of metal reinforcement embedded in the slab increases its strength. Woven wire mesh is the most common material for residential applications. For slabs on grade the Council of American Building Officials,32 One and Two Family Dwelling Code recommends 6x6 in.-W2.9 x W2.9 woven wire mesh. To help control cracking, it has been suggested that this is appropriate for a basement slab as well. 

The perimeter crack is located between the edge of the floor slab and the foundation wall. This applies to slabs in basements, crawlspaces, and slab-on-grade foundations. As a cold joint, this perimeter crack is always a potential radon entry point. Contractors building radon-resistant houses... 

If waterproofing or dampproofing treatments that are effective gas barriers and that can be sealed at joints and penetrations could be identified, then walls could be made radon resistant. Acceptable dampproofing or waterproofing treatments are specifically listed in building codes in many areas of the United States these lists are periodically amended as new materials come into use. These coatings apply primarily to basement walls. 

Tightened building shell to minimize the amount of air needed to pressurize the basement and to lower the neutral pressure plane.
