LD 50/60: the dose which will kill 50% of the exposed population within 60 days. LD 50/60 in this curve is about 450 cGy as measured in free air, without significant medical intervention. With timely, aggressive, appropriate, continuing medical support, the curve will be shifted to the right, and the LD 50/60 can be significantly higher than what is shown on this curve.

The conditions defining Case 1 do not hold.
The LD 50 is a standardized measure for expressing and comparing the toxicity of chemicals. The LD 50 is the dose that kills half (50%) of the animals tested (LD = "lethal dose"). The animals are usually rats or mice, although rabbits, guinea pigs, hamsters, and so on are sometimes used. In all these tests, the dose must be calculated relative to the size of the animal.
