STATISTICAL ANALYSIS OF DENSITY READINGS OF DUPONT 502 FILM BADGES AFTER EXPOSURE TO X-RAYS OF 0.07-MEV AVERAGE ENERGY

摘要

1.There is a significant linear relationship between density readings and exposure. The straight line was found to explain 99.67 percent the square of the correlation coefficient of the total variation.n2.When one reading from one badge has a density known to be associated with an unexposed badge, and three is doubt as to whether or not there has been any exposure, then the average exposure can be assumed to be blow 30 mr with 99 percent eon-fidence. For an average density found from 2 badges with 35 readings from each, the 99 percent confidence limit is 11mr
