KN-4006 series UV Radiation Treatment System
Method 2
：
Formula method
If the users can not find the value from appendix D, can use formula to calculation:
radiation time(s)= .
For example
：
If the radiation intensity is 4.0mW/cm
2
（the actual value please see table A-1 of appendix A）， and need the radiation
dosage 6.0J/cm
2
，we can calculate as follows ：
radiation time = = 1500（s） = 25（min）
That means it needs 25min .
