Key words:

• information entropy model

Abstract: Objective: To find a reasonable counting method to ensure the reserved amount of nucleus radiant prevention drug. Methods: Information entropy and Poisson distribution were used.Result and Conclusion: When 0.3、0.5、0.75、1 was chosen as Ko,while 5、10、20、30、50 as Ku,the range of radices of repertory amount of nucleus radiant prevention drugs was between 23 and 31,among which 23 was the smallest and 31 the biggest.Because of the uncertainty of number and the degree of injured,this result should take a further research.
