How much plutonium is needed to make a nuke?

For example, the U.S. Department of Energy estimated that about 9 pounds (4 kilograms) of enriched plutonium or Pu-239 would be enough to build a small nuclear weapon, though some scientists believe that 2 pounds (1 kilogram) of Pu-239 would suffice.

Is mercury really poisonous?

If you touch it, a small amount may pass through your skin, but not usually enough to harm you.

What is the most dangerous heavy element?

Polonium is a highly radioactive heavy metal. It is arguably the most lethal known material. Although it has some minor industrial uses it is best known for links with possible assassinations.

Is lead poisoning common?

Lead poisoning is very common. 1 in 40 children ages 1-5 years old have blood lead levels that are considered unsafe (over 5 µg/dL).

Can lead be absorbed through your skin?

A. Ways in which lead enters your body. … Lead can be absorbed into your body by inhalation (breathing) and ingestion (eating). Lead (except for certain organic lead compounds not covered by the standard, such as tetraethyl lead) is not absorbed through your skin.

Is plutonium man made?

Plutonium is a radioactive metallic element with the atomic number 94. It was discovered in 1940 by scientists studying how to split atoms to make atomic bombs. Plutonium is created in a reactor when uranium atoms absorb neutrons. Nearly all plutonium is man-made.
