What would you need to protect yourself from beta radiation?
Normal clothing will protect you from typical energy beta radiation.
Does a person exposed to radiation has no chance of survival?
Well, you are exposed to radiation every day and you survive... so the answer is NO. The radiation you are exposed to comes from many sources: sun, cosmic rays, medical imaging equipment, the ground, the air, your own body, etc.What is important with radiation (or anything else potentially toxic) is the total dosage received. With ionizing radiation this is usually measured in either REM (Roentgen Equivalent Man) or Sievert. 1 Sievert = 100 REM. The relative toxicity is measured statistically as the same dose does not have the same effect on different people, it is usually measured as LD50 (lethal dose for 50% of those receiving it). For ionizing radiation the LD50 is somewhere between 300 REM and 400 REM depending on the source you consult. This is a very high dose, the typical dose a person receives per year from all sources is about 0.1 REM so it would take at least 3000 years of normal exposure to approach LD50. For ionizing radiation the level where death is certain is somewhere around 10000 REM, at which the brain dies within minutes of exposure. At lower levels, even when death occurs the person can typically live weeks to months with reasonable medical care.Some other values of LD50:water, >90g/kgethanol, 7g/kgarsenic metal, 0.76g/kgaspirin, 0.2g/kgnicotine, ~0.05g/kgnerve gasses, a few micrograms/kgbotox, estimated 1 nanogram/kg
What type of radioactive decay is used in smoke detectors?
Most smoke detectors which operate alarms contain an artificially produced radioisotope: americium-241 in the form of americium dioxide. Americium-241 is made in nuclear reactors, and is a decay product of plutonium-241. It emits mostly alpha particles and relatively little harmful gamma radiation. The amount of americium in a typical new smoke detector is 1 microcurie or about 0.29 micrograms. The smoke detector works by using the americium as a source of ionizing radiation to ionize the air in an ionization chamber between two electrodes. The slightly ionized air allows a small current to be conducted between the two electrodes. When smoke enters the chamber, it absorbs some of the ionizing radiation, reducing or eliminating the current and triggering the alarm.
How much radiation is the average US Citizen exposed to during a typical year from TV and microwave ovens?
300 rem
Is a toaster using light energy?
Yes, it is. A typical toaster heats food by radiation from electrical heating elements. Most of the energy is invisible infrared radiation, although visible red light is also emitted.
What are the typical uses of lead?
Lead uses:- alloying element- material for pipes- ballast- radiation shielding- bullets- batteries- electrodesetc.
What is a typical day for a 9 year old in Germany?
It's typically 24 hours, roughly equivalent to a typical day for 9 year olds in other countries.
Is everyhting made of elements?
Not everything: electromagnetic radiation, beta radiation, gamma radiation, particle beams etc. are not formed from elements.
What is the origin name of Radon?
The name radon is derived from the Latin language word radius= radiation; the suffix on is typical for the noble gases (excepting helium).
What are the categories of tourism according to purpose of travel?
The categories of tourism traveling are typical ethnicity, heritage, sports, leisure, environmental, business, and special interest, and recreational.
How do humans use gamma ray energy?
The typical use for human-generated gamma radiation is in medical procedures, such as the "gamma knife" cancer therapy treatments.
What are the typical application areas of supercomputers?
Environmental modeling Financial modeling Atomic explosion modeling. Cryptography Data processing for big data experiments such as BABA and CERN.
