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 has been used in order to measure the effective radium content and radon exhalation rate. Results: The average values of the effective radium content ranges were from 2.30±0.179 Bq/kg to 3.07±0.254Bq/kg and the average values of radon exhalation rate range of 0.282±0.019 mBq/m2.day to 0.369±0.026 mBq/m2.day. Conclusion: The results coincide with the recommended OECD and ICRP's action level. In addition a good correlation was found between the effective radium content and radon exhalation rate in hair dyes samples.
