Twin chamber solid state nuclear track detector based dosimeters are used for estimating
radon (222Rn), thoron (220Rn) gases and their progeny concentrations in air. These …

Considering the role of radon in epidemiology, an attempt was made to make a nation-wide
map of indoor 222Rn and 220Rn for India. More than 5000 measurements have been …

Environmental radiation exists as a consequence of cosmic, terrestrial and man made
sources. Terrestrial radiation are emitted from natural radionuclide present in varying …

The use of more eco-efficient cements in concretes is one of the keys to ensuring
construction industry sustainability. Such eco-efficient binders often contain large but …

The γ-radiation emitted by building materials is calculated from the activity indices for 232
Th, 226 Ra and 40 K and expressed as the activity concentration index (ACI). Gamma …

Different methods for sealing sample containers for 222 Rn when measuring 226 Ra
through its progenies 214 Pb and 214 Bi using gamma-ray spectrometry have been …

This paper reports the analysis of soil radon data recorded in the seismic zone-V, located in
the northeastern part of India (latitude 23.73 N, longitude 92.73 E). Continuous …

The 19 towers constituting the CUORE detector are an assembly of ultra-radio-pure
components made of copper and PTFE plus tellurium dioxide crystals for a total of more than …

Radon emanation from the soil gas was studied using a deep red coloured cellulose nitrate
LR-115 type II film. The study was carried out from March 2012 to February 2013 at Mat …

Polyethylene terephthalate (PET) and polylactic acid (PLA) bottles were tested to evaluate
radon loss from water during 15 days of storage. PET bottles (lower surface/volume-ratio …
