The effective radium content and radon exhalation rate in hair dyes samples
Background: Hair dyes are the important materials widely used by various peoples in Iraq and other countries. The present work investigates the presence of the effective radium content and radon exhalation rate in hair dyes samples. Materials and Methods: Twenty hair dyes samples were collected from Iraqi markets. Sealed can technique using LR-115 type II plastic track detector s ha...
متن کاملRadium and radon exhalation studies of soil
Background: Everyone is exposed to radon because it is present everywhere with varying concentrations. Radon and its progeny are well established as lung carcinogenic. Materials and Methods: Track etch technique using LR-115 plastic track detectors has been used to measure the effective radium content and radon exhalation rates in soil samples collected from urban area of Etah district...

متن کاملEstimation of Radon Exhalation Rate and Radium Content in Soil Samples of Pathankot District, Punjab Using LR-115 Plastic Detector
In the present investigation, soil samples were collected from 10 villages belonging to Pathankot district, Punjab, India and assessed for radium content using LR-115 plastic detector. The ‘track etch’ technique has been employed for measuring the radium content. From the radium content, radon exhalation rates and mass exhalation rates were calculated for these samples. The mass exhalation rate...
متن کاملPhoton attenuation, natural radioactivity content and radon exhalation rate of building materials.
High concentrations of natural radionuclides in building materials can result in high dose rates indoors, from both internal and external exposure. In dose calculations, the main radionuclides of interest are 226Ra, 232Th and 40K. Usually much attention is paid to 226Ra due to 222Rn exhalation and the subsequent internal exposure. Other radionuclides of the uranium series such as 238U and 210Pb...
