You need to specify the units used to take the measurement. It could be presented in Sv, Gy, rad or mrem. (So I am asking you 0.3 what??)
Light radiation sickness begins at about
50-100 rad
0.5-1 gray (Gy)
0.5-1 Sievert (Sv)
50-100 rem
50,000-100,000 mrem
So if your measurement is in Rad - no it's not a lot. If it's in Gy or Sv then it is a significant dose, but will not cause acute sickness. If it's in rem then it's not a lot.
