Identify the normally radioactive material in the following list. [#1066]

Plutonium is the only radioactive element in the list. Plutonium is a radioactive, silvery-gray, metallic element with the symbol Pu and atomic number 94. It has a high surface tension and viscosity compared to other metals, and tarnishes when exposed to air. Plutonium is created in a reactor when uranium atoms absorb neutrons, and is a by-product of nuclear power plants. It is the main fuel in fast neutron reactors, and more than one-third of the energy produced in most nuclear power plants comes from plutonium. Plutonium has five common isotopes, each with a different half-life, which is the time it takes to lose half of its radioactivity

Crust The structure of the Earth is divided into four major concentric layers: inner core, outer core, mantle and crust (the outermost layer). The crust is made up of tectonic plates, which are in constant motion.

Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon). It looks like a very bright star. Venus is the brightest planet in the Solar System.

Normal body temperature is considered to be 37°C (98.6°F); however, a wide variation is seen. Among normal individuals, mean daily temperature can differ by 0.5°C (0.9°F), and daily variations can be as much as 0.25 to 0.5°C.

Outer Core The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.

Economics is the social science that studies the production, distribution, and consumption of goods and services, including wealth. Economics is divided into two classes, microeconomics and macroeconomics, and it directly affects everyday life. Economics is primarily concerned with analyzing the choices that individuals, businesses, governments, and nations make to allocate limited resources. Economic models emerged from the broader field of political economy in the late 19th century.
