In my experiment,I am making a curve of cell survival under UV light.
UV light tube; 30W, 254 nm,distance to subject: 78cm, exposure time: 10 Sec
and 60 Sec.
How to calculate to get a dose of UV light at 10 Sec and 60 Sec with unit (
KJ/(M^2)) ?
Thanks a lot.

easiest way just borrow a hand hold uv meter and you can read the dosage
right away.
