| Abstract:: |
| Objective To investigate the typical value of gamma-radiation dose rate and its confidence interval in tank-transported copper ore by using bootstrap resampling techniques. Methods Bootstrap resampling method, coupled with kernel density estimation, introduced to acquire the typical value of gamma-radiation dose rate in copper ore. Results The typical value of gamma-radiation dose rate in copper ore was expressed as the central tendency of the means of resampling, and two kinds of confidence interval, empirical percentile and bias-corrected accelerated confidence interval, were provided as standard error. Conclusion It is clearly demonstrated that this method has an advantage to give a robust description in explanation of central tendency and variation range of gamma-radiation dose rate data profiles. |
