What does LD50 mean?

Panel 1:
The question, â€œWhat does LD50 mean?â€ appears at the top of the panel. Below and to the left is the text, â€œLD50 stands for lethal dose 50. It refers to the amount of a chemical that will kill half of the subjects exposed to it.â€ At the left of the panel is what looks like an oil drum with a dark liquid oozing out of it. The drum has a skull and cross bones on its side.
Panel 2:
In white text on a dark background are the words, â€œLD50 comes up in regard to falling in this way:â€ Below, in black text in a square white box are the words, â€œFrom what height is it expected that half the people who fall that distance will die, while the rest survive?â€
Panel 3:
At the right of the panel is a drawing of â€˜Cocky,â€™ the mascot for the University of South Carolina Gamecocks. Cocky is standing and wears a jersey with â€˜Carolina 01â€™ on it. Cockyâ€™s left hand is held high with thumb and pinky finger extended in the â€˜shakaâ€™ (or hang loose) hand sign. To Cockyâ€™s left is the following text, â€œA 2017 study by University of South Carolina researchers concluded that the LD50 for falling was 48 feet.â€
Panel 4:
At the left of the panel are two bar-chart bars. The one on the left has the words â€™48 feetâ€™ inside it and the number 50% right above it. To its right is a longer bar with the words â€™84 feetâ€™ inside it and the number 90% right above it. At the top of the panel near the number 90% is a figure of a falling person in a dark, long-sleeve shirt and somewhat lighter long pants. Below that figure and to the right is the text, â€œAt 84 feet, the death rate increased to about 90%. In other words, only one of every ten people who fall that far will survive.â€
This cartoon is part of a series called Falling. It is written and drawn by Jim Hamilton who can be found on Instagram at Green Harbor Publications (all one word, greenharborpublications).
