This half-life is short enough to restrict transport by pure diffusion to short distances only, but once the radon has left the solid material and has become mixed with air, convection transport over longer distances (several meters) from the soil into both outdoor air and indoor environments ...
Estimation of indoor radon, thoron and their progeny using twin cup dosemeters with solid-state nuclear track detectors in Digboi of Upper Assam The seasonal variations of indoor radon, thoron and their progeny levels were studied in 20 houses situated in the oil-rich areas of Digboi of Upper ...
The detectors will be used in a survey of 2000 or more homes in the UK. The response of the dosemeters is shown to be linear with respect to exposure. It is shown that snap-on polyethylene lids allow 222 Rn to diffuse into the detector cup while excluding radon daughters, dust and ...

The bottom line.Gamma measurements made with simple hand-held meters alone CANNOT tell you how much radon is being produced by your natural stone materials. These simple meters grossly over-respond to the actual radiation coming from the stone surface. ...
ranging typically from a few meters (for hand dug wells) to a several hundred meters of depth65,66. Generally, water wells in Canada are drilled to the depth at which the water well driller ascertains that groundwater can be pumped out of the well at a sufficient rate for the required ...

According to the year of construction/foundation, educational institutions can be divided into three categories: (I) 1950–1965 (“minimalism of Khrushchev”); (II) 1965–1980, a larger standard of square meters per child; and (III) 1980–2020, more spacious buildings that are typical of nurs...
Sooner or later the inspector will miss a "wet spot". Mold needs moisture to grow (food and water). Infrared cameras and moisture meters are essential to identify "wet spots" that can grow mold. Your Naples home will almost always have mold spores in the indoor air but like most living...
Equipment used during a mold assessment (inspection)include moisture meters, temperature & humidity measuring devicesinfrared cameras, safety masks, particle counters to name just a few. Professional Mold Assessors use these "tools" Bonita Springs &Cape Coral Inspectors ...
