Answer to Question 1

Every home has one, they eventually must be replaced, and the oldest models used
huge amounts of energy. The reduction in energy use by refrigerators has saved building a
substantial number of generating facilities.

Answer to Question 2

Table 20.8 says that there will probably be 1 cancer per 100 Sv. So, the collective
dose of 100 person-sieverts will probably lead to a single cancer in this group.

Asthma-like symptoms were first recorded about 3,500 years ago in Egypt.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
