clearance level level of being free of significant risk from radiation Explanation: This is the first one up from zero. Below this, the person being tested is considered clear of significant risk of radiation contamination. Above it, he/she is at risk to some extent specified by a higher rating. |

clearance level level of radioactivity below which waste material may be treated as non-radioactive Explanation: The concept is slightly different from what Jack Doughty has suggested. "As is the case overseas, Japan too is looking to introduce a 'clearance level' for radioactive waste. Under this system radioactive waste with less than a certain concentration of radioactivity will be treated as 'waste which does not need to be treated as radioactive waste'." http://www.cnic.jp/english/newsletter/nit100/nit100articles/... -------------------------------------------------- Note added at 5 hrs (2016-09-21 20:07:48 GMT) -------------------------------------------------- According to the diagram, an individual exposed to clearance level radioactivity would receive 10 micro Sievert in one year. |
