An awareness film about cancer by U.S. Public Health Service, United States, titled 'Choose to Live'. Dramatization shows a woman's experience with cancer. Building of United States Public Health Service in Washington D.C. Thomas Parran, Surgeon General, U.S. Public Health Service speaks about cancer and victims of cancer. View of women work at telecommunications, man at farm and men in urban area -- anyone can be vulnerable to cancer. He tells the probability of death from cancer. He talks about a woman Mary Brown. Her family sits at a dining table and has a breakfast meal together. She waves goodbye. Brown finishes her household work and looks at a meeting note. Meeting for cancer awareness at a club. A doctor talks about diseases. He compares its hazards with deaths in the World War. He discusses scientific investigation and research against cancer. Scientists work in laboratories. Lab worker run experiments injecting mice with chemicals. Beakers, test tubes, distillation equipment, mouth suction tube seen. Scientist looks through microscope.

Bill designating one month each year as Cancer Control Month signed by U.S. President Franklin D. Roosevelt. A doctor prepares for surgery. A team performs a surgery. An X-Ray machine. Control panel of the X-Ray machine. The third method of treatment is by the use of radium. Shows sand equal to all the radium available in the U.S. Man takes out radium from lock, he puts it on an applicator and takes it to a treatment room. Nurse measures the treatment area of patients body to apply radium treatment. Radon mercury forces gas. Man cuts pieces and collect it. Men sit at a cancer clinic. Man talks with a doctor. Doctors examine and treat cancer patients. Doctor observes X Rays. Doctor shows and explains the symptoms of cancer. Scientist study in a laboratory. Men women at a public meeting. Cancer awareness banners. Location: United States USA. Date: 1942.

A NATIONAL REPORT SAYS THE MINIMUM LEVELS OF HOUSEHOLDS RADON GAS ARE SET TOO LOW AND MUCH OF THE NATION IS AT RISK AS A RESULT.

Uranium decay chain products with half-lives, animation. The radioactive isotope uranium-238 decays by the breakdown of its unstable nucleus,. The products are a succession of other radioactive isotopes, culminating in the stable isotope lead-206. The particles in the nucleus are protons (red) and neutrons (yellow). Three types of radiation are produced: beta particles (electrons, blue), gamma radiation (orange) and alpha particles (red and yellow). The first decay produces thorium-234. The next decay produces proactinium-234, followed by uranium-234, thorium-230, radium-226, radon-222 and polonium-218. Subsequent decays produce isotopes such as astatine-218, lead-214, bismuth-214, thallium-210, polonium-214, lead-210, mercury-206, bismuth-210 , thallium-206 and finally lead-206. This is known as the radium series (also called the uranium series). For animations of the decay chain, see clip K008/5467 and K008/5468.

Uranium decay chain, animation. The radioactive isotope uranium-238 decays by the breakdown of its unstable nucleus, producing various forms of radioactivity. The products are a succession of other radioactive isotopes, culminating in the stable isotope lead-206. The particles in the nucleus are protons (red) and neutrons (yellow). Three types of radiation are produced: beta particles (electrons, blue), gamma radiation (orange) and alpha particles (red and yellow). The first decay produces thorium-234. The next decay produces proactinium-234, followed by uranium-234, thorium-230, radium-226, radon-222 and polonium-218. Subsequent decays produce isotopes such as astatine-218, lead-214, bismuth-214, thallium-210, polonium-214, lead-210, mercury-206, bismuth-210 , thallium-206 and finally lead-206. This is known as the radium series (also called the uranium series). For this animation without labels, see clip K008/5468. For the radiation associated with each decay, see clip K008/6238.

Animation of the decay chains of a uranium-238 nucleus. U-238 is a radioactive element with 92 protons (red), indicated to the lower left of its chemical symbol, and 146 neutrons (yellow), giving it a total atomic mass of 238 (upper left of symbol). It is unstable, and decays by emission of an alpha particle, which consists of two protons and two neutrons. This produces thorium-234. Th-234 undergoes beta decay, in which a neutron converts into a proton by emitting an electron (blue) and an electron antineutrino (orange), forming a protactinium-234 nucleus. These processes continue, from Pa-234 to U-234 to Th-230, radium-226, radon-222 and then to Polonium-218. Po-218 can decay by both beta (left) and alpha (right) decay, forming astatine-218 and lead-214 respectively. These both decay to bismuth-214, which can again decay both ways, forming thallium-210 by alpha decay (left) and Po-214 by beta decay (right). These both decay to Pb-210, which decays to mercury-206 by alpha decay (left) or Bi-210 by beta decay (right). These both decay to Tl-206, which decays to Pb-206. This isotope of lead is stable, and is the end of the decay chain. Naturally occurring uranium contains a combination of all of these nuclei. They have different half lives, from the 4.5 billion years of U-238 itself to as little as 164 microseconds for Po-214.
