- Leukocytes (200 leukocytes/sample of one donor) were irradiated with increasing doses (0-8 Gy) and mixed in equal proportions with the next higher irradiation dose level sample. Comparison of mean DNA damage in %Tail DNA for samples treated with 0, 2, 4 or 8 Gy and mixtures (0 and 2 Gy, 2 and 4 Gy, 4 and 8 Gy) revealed significant differences for almost all pairs and a trend for cells irradiated with 2 Gy vs. 2 + 4 Gy.
- Abbreviations: SD = standard deviation, p-value = probability value, F-value.
