For the purpose of this article, I will be referring to the conversion of existing buildings of a different use to self-storage. These buildings may include retail stores, office buildings, schools, hotels, industrial buildings, and miscellaneous properties such as abandoned bus stations, underground parking lots, etc.
Bioassays: Background Information. A bioassay involves use of a biological organism to test for chemical toxicity. Perhaps the oldest and most commonly known example is the canary in the coal mine. Traditionally, coal miners have taken caged canaries down into the mines to help ensure a safe air supply.
Bone Density. Guide. A bone density test measures the density of minerals (such as calcium) in your bones using a special X-ray. This information is used to estimate the strength of your bones. We all lose some bone mass as we age. DXA can measure as little as 2% of bone loss per year. 2  It is fast and uses very low doses of radiation. 3  Single-energy X-ray absorptiometry (SXA) may be used to measure heel and forearm bone density, but SXA is not used as often as DXA. 4  Peripheral dual-energy X-ray absorptiometry (P-DXA). 5  P-DXA is a type of DXA test.
