Compared with JJG 825-1993, in addition to editorial changes, the present regulations the main technical changes are as follows. --- Relaxed radon volume activity in response to the amount of deviation limit; --- Instrument tightness canceled checks; --- Provisions measuring radon volume activity in response to the measurement range 3-point calibration measurements of the average (see 7.3.4); --- Increasing the relative intrinsic error test item (see 7.3.5). Radon monitor1 ScopeThe order applies to the measurement range (0 ~ 10) kBq · m-3 radon environment (specifically refers to 222Rn, under Same) volume activity meter initial verification, subsequent verification and the use of checks. 2.
