Dear friends,
I am working on one 300 MHz NMR. I found that if I continue work on this
instrument for a few hours, I will have dizzy and headache symptom. There
is one ventilative fan and two air conditioners in the room. The oxygen
level is fine. I am also working in another lab to take care GC, FT-IR and
elemental analyzer but I don't have any health problem.
I wonder whether it is due to magnet. The computor is about 1.5 meter away
from 5 gause line. This NMR instrument was installed 6 years ago. I found I
got headache problem since last year.
Did anybody experience this problem before?
I would be very appreciated if anyone could give information.
Best regarda,
Yanling Hua
