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

Marie Salomea Skłodowska–Curie
She was the first woman to win a Nobel Prize, the first person to win a Nobel Prize twice, and the only person to win a Nobel Prize in two scientific fields. Marie won her 1st Nobel Prize in 1903 in Physics with her husband for their pioneering work developing the theory of "radioactivity" - a term she coined. Marie won her 2nd Nobel Prize in 1911 in Chemistry for her discovery of the elements polonium and radium, using techniques she invented for isolating radioactive isotopes.

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.

Blue colour of the sky is due to dispersion or scattering of light. The two most common types of matter present in the atmosphere are gaseous nitrogen and oxygen. These particles are most effective in scattering the higher frequency and shorter wavelength portions of the visible light spectrum.

Non Luminous Moon is non-luminous. It do not produce light, it shines by reflecting the sunlight falling on it.

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.
