dc.description.abstract This research shows that the moon circulation and motion affects air ionization , where the number of negative ions decreases as the ionization potential decrease as the moon day increases when the sun shine from 3 ok to 5 ok . But at the time interval from 6 ok up to 9 ok the number at negative ions increases gradually from the 5th moon day where it attains its maximum value at the 8th moon day , then it decreases gradually up the 14th moon day. The sun motion also affects the number of negative ions , where it becomes large at 3 ok then decreases gradually up to 6 ok as far as it becomes constant after that up to 9 ok . this confirms the role of sun radiation in increasing the number of ions since degree of ionization decreases as the radiation intensity decreases , then it becomes constant at night when no radiation exists. It was also observed that the number of negative ions increases near plants compared to regions far from the plants. en_US
