“…Radium contents range between 0.0415-0.249 Bq/Kg, with 0.115 Bq/Kg as a mean value. Comparing with the other available Fundamental and applied physics measurements its very low than the results of 7.9-37.6 Bq/Kg estimated in reference [25]. In the kohl sample, the radium concentration is 0.105 Bq/Kg which is lower than 0.866 Bq/Kg the results of reference [26].…”

Cosmetics play an important role of human external appearance, its products used to alter or enhance the facial appearance or the body and skincare, currently worldwide consumed with frequently use increasing the human body exposure to the various chemical elements including radioactive substances. This research aimed to measure the concentrations of alpha emitters, and the annual effective dose AED resulting from radon intake. LR-115 track detector used to measure radon, and radium concentrations in 20 cosmetics samples selected from markets. In this work the concentrations of radon in the samples found to vary from 9.876 to 30.97 Bq/m 3 with 22.11 Bq/m 3 a mean value, this mean value is a very small than 100 Bq/m 3 the reference level limits of the World Health Organization (WHO). The annual radon effective dose varied between 0.249-0.781 mSv/y which is within the range of 0.2-10 mSv/y (UNSCEAR). Radium contents vary between 0.041-0.249 Bq/Kg with 0.115 Bq/Kg as a mean value. This work identified law measured concentrations of radionuclide present in cosmetics showed its safe for use.

The study investigates commercially available negative ion clothing, and evaluations are made using gamma-ray spectroscopy and Geant4 Monte Carlo simulations. Observed to contain naturally occurring radioactive material (NORM), evaluations are made of the radiological risk arising from the use of these as items of everyday wear, undergarments in particular. Organ doses from these were simulated using the MIRD5 mathematical female phantom, with the incorporation of dose conversion factors (DCFs). At 175 ± 26, 1732 ± 247, and 207 ± 38 Bq, for 238U, 232Th, and 40K respectively, item code S05 was found to possess the greatest activity, while item code S07 was shown to have the least activity, at 2 ± 0.5 and 15 ± 2 Bq, and again for 238U and 232Th, respectively. Sample code S11 recorded least activity, at 29 ± 5 Bq, for 40K. Among the clothing items, sample item code S05 offered the greatest concentrations of Th, U and Zr, with percentage means of 1.23 ± 0.1, 0.045 ± 0.001, and 1.29 ± 0.1, respectively, giving rise to an annual effective dose of 1.57 mSv/y assuming a nominal wearing period of 24 h per day. Accordingly, the annual public dose limit of 1 mSv can be exceeded by their use.

“…Papadopoulos et al [15] tested various commercial cosmetic clays which have different color by using X-ray powder diffraction. Milena-Pé rez et al [16] studied the side effects of the plant extracts and raw materials which used for therapeutic and beauty purposes. The results uncovered that no radiological risk derived from the use of these samples.…”

The nuclear track detector CR-39 is used in the detection of radon gas concentration in selected samples of cosmetics in the local market. Products of wide use are selected and employed in the current study. Six types of cosmetic products of different origins are tested by taking equivalent quantities of these products and putting them in plastic boxes. The detector is left with the samples for a period of 50 days. In addition to measuring the rate of surface evaporation of radon gas, measurements of the annual equivalent dose of radon gas are also carried out. The results show that the highest concentration of radon gas is in Charcoal Facial SCRuB (American origin) and it is equal to 0.0795 Bq/m3, whereas the lowest one in "bb" cream basis (5 in 1) is equal to 0.0355 Bq/m3. Based on specific international organizations and agencies, the concentration of radon in the samples under consideration is within the acceptable limits.
