How is one millirem written in a scientific notation?
One millirem in a scientific notation is written as 10-3 rem.
In scientific notation one millirem is written how?
One millirem is 1 x 10-3 rem, which can also be written as 1E-3 rem. Note that 1 x 10-3 is not the same as 1.0 x 10-3 which is not the same as 1.00 x 10-3. Those numbers have one, two, and three significant digits, respectively. That is, the second number is more precise than the first, and the third is more precise than the first two.
What is 2200 millirem to rads?
2200 millirem = 2.2 rad
How is one millirem written in a scientific notation?
One millirem in a scientific notation is written as 10-3 rem.
How much natural radiation is the average person exposed to in a year?
About 100 millirem.
How much radiation was given to the people after the TMI accident?
1 Millirem. Which is less than their yearly dose.
How is one millirem written?
One million is written like this: 1,000,000 or in scientific notation, 1 x 106
Smoke detectors are they safe for us?
Yes, even though they do emit ionizing radiation. The amount of radiation emitted from a smoke detector is about 1 hundredth of a millirem per year. The background radiation from radioactive isotopes in the ground is about 300 millirem per year. So the ground your standing on right now is exposing you to more radiation then your smoke detector ever will.
2.4 mSv converted to mrem?
The term mSv is a Millisievert and the term mrem is a Millirem, both used in radiation to measure a dosage. 2.4 mSv is equal to 240 mrem.
In scientific notation one millirem is written how?
One millirem is 1 x 10-3 rem, which can also be written as 1E-3 rem. Note that 1 x 10-3 is not the same as 1.0 x 10-3 which is not the same as 1.00 x 10-3. Those numbers have one, two, and three significant digits, respectively. That is, the second number is more precise than the first, and the third is more precise than the first two.
What are the units of radiation doses?
Sieverts and milliSieverts are used now. They replaced the old rem and millirem. There is a factor 100 difference, so 1 Sievert = 100 Rem. The current limit for nuclear industry employees is 20 milliSv/year, though the actual average level in the US is about 2.4 milliSv.
How would you write one hundred million in scientific notation?
100 million in Scientific Notation = 1 x 108
What is natural radioactive decay?
GLOSSARYNATURALNORMRADONRadiation is a natural part of the earth's environment. It comes from the sky above us, the earth beneath us and even from our own bodies. The air we breathe and the food we eat contain some naturally occurring radioactive materials. In fact, on average a person in the United States receives a radiation dose of about 300 millirem per year from natural sources compared to a dose of about 50 millirem per year from "artificially produced" sources such as medical x-rays.Radioactive materials in rocks and soilNatural radioactive material in rocks and soil account for about 28 millirem or 8% of the radiation dose a person typically receives in a year from all sources (including medical exposures). The earth's crust contains small amounts of uranium, thorium, and radium as well as radioactive isotopes of several elements including potassium. The radiation dose comes from the gamma rays which are emitted from the rocks, soil and some building materials (such as bricks and concrete).Radon in indoor airSmall amounts of radon, a radioactive gas which comes from the radioactive decay of uranium, seep into the atmosphere from the soil. On average, inhalation of the radon in homes and other buildings accounts for 200 millirem per year. This is about 55% of the total radiation dose an individual receives in a year from all sources, including medical x-rays, cosmic rays, building materials, the earth's crust, and ingested radioactive materials.Radioactive materials in the bodyAbout 11% (40 millirem) of our radiation dose comes from naturally occurring radioactive materials in the body. Most of the dose comes from a radioactive isotope of potassium. Radioactive potassium-40, as well as other radioactive materials (such as carbon-14) which occur naturally in air, water, and soil are incorporated into the food we eat and then into our body tissues.Cosmic raysCosmic radiation comes from outer space. The radiation dose from cosmic radiation increases with altitude, roughly doubling every 6,000 feet. Therefore, a resident of Florida (at sea level) on average receives about 26 millirem, one-half the dose from cosmic radiation as that received by a resident of Denver, Colorado, and about one-fifth of that by a resident of Leadville, Colorado (about two miles above sea level). A passenger in a jetliner traveling at 37,000 feet would receive about 60 times as much dose from cosmic radiation as would a person standing at sea level for the same length of time.The millirem is the term used to describe the amount of radiation absorbed in the body, adjusting for radiation type.
What are some eight letter words with 4th letter L and 5th letter I and 6th letter R?
According to SOWPODS (the combination of Scrabble dictionaries used around the world) there are 1 words with the pattern ---LIR--. That is, eight letter words with 4th letter L and 5th letter I and 6th letter R. In alphabetical order, they are: millirem
