Question

5. The survival rate (i.e., the chance of survival) $S(D)$ of clonogenic cells (cancer cells) exposed to a radiation treatment can be modelled by $S(D) = e^{-0.5D^2 - D}$ where $D \ge 0$ represents the applied radiation dose (measured in grays, Gy). (a)[2] What is $S(0)$? Does it make sense? (b)[3] Sketch the semilog graph (use $\ln$) of the survival rate for $D \ge 0$. Label the axes.

5. The survival rate (i.e., the chance of survival) S(D) of clonogenic cells (cancer cells)
exposed to a radiation treatment can be modelled by
S(D) = e^-0.5D^2 - D
where D ≥ 0 represents the applied radiation dose (measured in grays, Gy).
(a)[2] What is S(0)? Does it make sense?
(b)[3] Sketch the semilog graph (use ln) of the survival rate for D ≥ 0. Label the axes.

5. The survival rate (i.e., the chance of survival) S(D) of clonogenic cells (cancer cells) exposed to a radiation treatment can be modelled by $$S(D) = e^{-0.5D^2 - D}$$ where D≥ 0 represents the applied radiation dose (measured in grays, Gy). (a)[2] What is S(0)? Does it make sense? (b) [3] Sketch the semilog graph (use In) of the survival rate for D≥ 0. Label the axes.
