Why is external criticism so important when it comes to analyzing?
There is no external criticism.
Why is external criticism so important when it comes to analyzing data?
There is no external criticism.
Where does background radiation originate?
Background radiation can come from all sorts of sources, some natural, some man-made.Examples include...cosmic rays from spaceradon gas emitted from the earth's crustelectromagnetic radiation from a number of possible sourcesatomic radiation from nuclear substances.For much more information see Related links below this box.
Where does background ultraviolet radiation come from?
it comes from space circle jerk
What comes first mutation or natural selection?
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
What we can do for radiation exposure?
help me to stop it. It is pulsed radiation that comes into my home and onto my property .
Skin cancer can be caused by too much exposure to what?
Ultraviolet radiation that comes from the sun.
Just under half of mans exposure to external radiation comes from?
The answer is probably the electromagnetic waves from power lines and personal electronic equipment like cell phones, computers, and televisions, followed by radio and microwave. The number one is most likely the sun.
Is food and drink a natural source of radiation?
Most background radiation comes from natural sources, while most artificial radiation, plants absorb radioactive materials from the soil and these pass up the food chain.
Does most of the radiation exposure for an average citizen in the US come from nuclear power plant operation and early atmospheric nuclear weapons tests?
No, radiation from these sources is negligible. Most comes from natural background, which depends a lot on the geology of the area. Radon is usually the biggest factor (see the link below)
How much radiation do you get from naturally radioactive foods?
All foods have at least a trace of radioactive material in them. It is something that cannot be avoided, and the radiation comes from the materials in nartual background radiation. There is a bit more to this, so let's look.There is natural radiation all around us. There always has been. And in the last century, which has seen man fooling around with all manner of radioactive material (and making a lot more of it!), the background radiation level has gone up. We know about nuclear tests and nuclear accidents, don't we? But, generally speaking, natural background radiation does not pose much of a threat to people. Not the stuff we breathe, not the stuff we eat, and not the stuff we walk around near and get exposed to.There should be concerns among some groups of people who live in areas where radon can occur in modest amounts. These folks should have their homes checked for radon accumulation. But beyond that, there is little to fear from the threat of radiation exposure owing to natural sources. It is much more likely for many folks to die in traffic (or other) accidents than to die from radiation sickness, or from cancer brought on by radiation exposure.
How did the radio impacted lives in a negative way?
Radio wave Radiation comes from radios and their communication towers so continued exposure can cause cancer = bad impact
What is a simple definition of microwave radiation?
microwave radiation is radiation that comes from microwaves
How does melanin typically respond to ultraviolet radiation?
Melanin serves as a shield against UV exposure, which comes in the form of a tan that occurs when melanin pigments enlarge in response to UV radiation. By doing this, the skin helps to prevent sunburn damage, which can lead to cancerous melanoma.
What are the three radiation that comes from the sun?
Ultraviolet Radiation,Visible Light,Infared Radiation
How is nuclear radiation harmful?
Radiation of any type speeds up the growth rate of cells and in high doses can cause burns. The ever-so-common sunburn is actually a radiation burn because the sun gives off radiation. This is also why people who stay out in the sun without proper protection from it are more likely to get skin cancer. This is because skin cancer is the rapid and uncontrolled growth of cells.
What will happen if the epidermis blocked all UV radiation from reaching the blood vessels in the dermis?
Nothing in particular, because that happens anyway, especially in people that have skin that is highly pigmented. The UV radiation the comes in contact with the keratinocytes, special cells that protect the skin, in the upper layer,the epidermis are the ones that become cancerous from UV radiation exposure.
