Question
Chapter 38, Problem 1DAA
Summary Introduction
To find: How many would die of a radon induced lung cancer, if 1000 smokers were exposed to a radon level of 1.3 pCi/L over a lifetime.
Concept introduction: Radon is an odorless gas which increases the risk of lung cancer. Radon increases the risk of cancer in smokers compare to the non smokers. It is a noble gas which is radioactive, colorless, odorless and tasteless. It is produced by the radioactive decay of radium-226.

compounds where scientists study what happens to human bodies
after death. Bodies that are donated for scientific study are left
outside designated areas. Their decay is tracked under various
conditions (heat, cold, humidity). The observations and data
collected contribute to forensic scientists' understanding of the
factors that impact how a body changes after death
timeline of what happens after death is a useful tool for doctors and investigators. As you have seen, most
ese changes overlap and are influenced by outside factors, So investigators never rely on only one to two
ese indicators. All the clues from the body, combined with clues from the scene, are needed to paint the
icture of what occurred.
e Markers: Clues are also left at the scene, often referred to as scene markers, that help establish a
re. These markers may include dated texts, emails, or mail, a broken clock, or even dishes in the sink.

- Polonium is a rare element with 33 radioisotopes. The most common one, 210Po, has 82 protons and 128 neutrons. When 210Po decays, it emits an alpha particle, which is a helium nucleus (2 protons and 2 neutrons). 210Po decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason that authorities failed to discover toxic amounts of 210Po in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of 210Po become after it emits an alpha particle?arrow_forwardMany people have died from taking a prescription drug because an error was made in the concentration on the label of the drug.

- Dogs used as subjects in laboratory experiments live in stacked metal cages with only fluorescent light, never walk on grass, and associate humans with pain. In toxicology testing, they are exposed to toxins at increasing levels to determine at what point they become ill. Before a beagle can be rescued, the laboratory has to agree to release it, which can be a challenge. If the laboratory is willing, the Beagle Freedom Project still has to negotiate, which usually means paying for all costs, including veterinary care and transportation, and absolving the laboratory of all liability, and then find the dog a home. Alternatives to testing on beagles include three-dimensional human-skin-equivalent systems and a variety of advanced computer-based models for measuring skin irritation, for instance. According to the New England Anti-Vivisection Society, nonanimal tests are often more cost-effective, practical, and expedient; some produce results in a significantly shorter time.
