The results show that the rate of micronucleus and nuclear abnormity, and CAT activity increased gradually, the number of WBC descended in low dosagerange.
On basis of establishing the dosagerange of sand-consolidation agents and porosity-increasing agents, CA-CC and BS-BZ as the main components of two sand-consolidation agents were selected.
Lower speed films produce images of good resolution and dynamic range but requires more photons for exposure and increases the radiation dosage of the subject.
