Consultation: absorption measurement and equivalent measurement

Dosimetric quantities: specific release kinetic energy, exposure, specific conversion energy, absorbed dose. Radioactivity: activity, specific kinetic energy rate constant of air. Basic quantities of radiation protection: dose equivalent (recommended after ICRP60 report), equivalent dose and effective dose. Protective dose cannot be measured directly, but dosimetry and radioactivity can be measured. Auxiliary protective dose: equivalent dose that should be accumulated, effective dose that should be accumulated, dose burden and collective effective dose. Actual dose of external radiation protection: environmental dose equivalent, directional dose equivalent, personal dose equivalent. Effective dose is generally used in the low dose range, mainly for managers to control the probability of random effects. In the high dose range that may cause tissue reaction (deterministic effect), it is necessary to estimate the absorbed dose and consider the appropriate relative biological effect to evaluate the radiation effect. For example, in the Chernobyl accident in the former Soviet Union, the deterministic effect was considered in the dose assessment of workers near the core and on the nuclear island. The actual dose equivalent defined by ICRU is an indirectly measurable quantity, which is used to calibrate the radiation instrument. In daily monitoring, these dose equivalents can be considered to be accurate enough to estimate the effective dose and skin dose respectively, especially when the values are less than the protective limit. In the normal operation of nuclear power, the indicated value of the instrument is usually less than the protection limit, which considers the random effect. These quantities refer to people, not individuals. Because individual differences exist, this is very important. In addition, the random effect is only a probability problem. The higher the dose, the higher the probability of cancer, but the severity of the consequences has nothing to do with the dose. To put it bluntly, it's cancer. It's all over. Remember the probability problem here, or the probability problem. The incidence of cancer is the statistical result of a large number of people, but this large number of people is actually a limited population, and the statistical process can not overcome the purity and relative identity of other factors between the control group and the observation group. Therefore, the statistical process and statistical value are also a reference value. Just look at it, don't listen to the wind and rain, and scare yourself out of order. I'm incompetent, and it's a little hard to sort things out in my mind. What is wrong, especially the technical content, I hope to point it out. * * * Progress has been made. In addition, I suggest you put such problems in the column of radiation protection?
