摘要

到目前为止，对化妆品(如粉饼和眼线笔)的放射性测量还没有报道。本文采用伽马能谱法和CR-39固体核径迹探测器对6种不同品牌的化妆品进行了研究。结果表明，238U、232Th和40K的比活度平均值分别为12.66±2.96、14.58±8.83和269±120 Bqkg−1。氡平均呼出率为0.21±0.04 Bqm−2h−1。计算出的镭当量低于推荐值(370 Bqkg−1)。所研究样品的自然放射性吸收剂量率范围为6.83±2.6 ~ 99.5±51 nGyh−1。x射线荧光光谱研究表明，重Mo、Sr、Pb、Zn、Cu、Ni、Fe、Mn、Rb、As、Zr和Cr的浓度分别为4±0.96、26.93±12.24、110135±109973、672.98±433、1001±722、318±145、3847±790、60±25、24.71±13、9002±4210、24.71±18和153±72 ppm。

Studies of radioactive contaminations and heavy metal contents in cosmetics

Measurement of radioactivity in cosmetics such as face powders and eye liner (kohl) has not been reported so far. Herein gamma ray spectrometry and CR-39 solid state nuclear track detector have been used to investigate six cosmetics of different brands. The results have demonstrate that the average values of specific activities of 238U, 232Th and 40K were 12.66±2.96, 14.58±8.83 and 269±120 Bqkg−1, respectively. Also the average radon exhalation rate was 0.21±0.04 Bqm−2h−1. The calculated radium-equivalents were lower than recommended value (370 Bqkg−1). The absorbed dose rates due to the natural radioactivity of the investigated samples ranged from 6.83±2.6 to 99.5±51 nGyh−1. Also, X-ray fluorescence spectrometry studies showed that the concentrations of the heavy Mo, Sr, Pb, Zn, Cu, Ni, Fe, Mn, Rb, As, Zr and Cr were 4±0.96, 26.93±12.24, 110135±109973, 672.98±433, 1001±722, 318±145, 3847±790, 60±25, 24.71±13, 9002±4210, 24.71±18 and 153±72 ppm, respectively.
