108 BIOLOGICAL EFFECTS OF LOW LEVEL EXPOSURES

Figure 5.10. Relationship between cell viability and radiation-induced augmentation.

Spleen cell suspensions were irradiated in vitro and placed in cultures with

SRBCs as antigen. Results represent average of two experiments

harvested on day 4. Similar results (not shown) were obtained with analyses

on day 5. Adapted from Anderson and Lefkovits.16

Figure 5.11. Influence of small increments of irradiation upon in vitro response to SRBCs.
Spleen cells were irradiated in vitro and placed in 1-mL cultures with SRBCs
as antigen. Data represent plaque-forming cells (PFCs) on day 4. Similar
results obtained on day 5 (data not shown). Adapted from Anderson and
Lefkovits.16
