What causes nuclear fallout?
Fallout is the radioactive particles that fall to earth as a result of a nuclear explosion. This radiation hazard comes from radioactive fission fragments with half-lives of seconds to a few months, and from soil and other materials in the vicinity of the burst made radioactive by the intense neutron flux.
What causes radiation poisoning?
Acute Radiation Syndrome (ARS) (sometimes known as radiation toxicity or radiation sickness) is an acute illness caused by irradiation of the entire body (or most of the body) by a high dose of penetrating radiation in a very short period of time (usually a matter of minutes).
What keeps radiation out?
Shielding: Barriers of lead, concrete, or water provide protection from penetrating radiation such as gamma rays and neutrons. This is why certain radioactive materials are stored under water or in concrete or lead-lined rooms, and why dentists place a lead blanket on patients receiving x-rays of their teeth.
What is the most common cause of health problems resulting from radiation?
Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness”). It can also result in long-term health effects such as cancer and cardiovascular disease.

Can you get dog ear plugs?
Earplugs can be made by dampening a piece of cotton wool and squeezing out any excess water. The cotton wool is then rolled into a cylindrical shape and twisted into the dog’s ear as to pack the canal. The plug should be secure and firm, but not so tight as to irritate the dog.
