What cell types is least injured by radiation?
Cells with no nucleus. Radiation affects actively dividing cells most. Even cells that are not dividing but contain a nucleus can be affected because the radiation damages the DNA. A cell without a nucleus lacks DNA to be damaged and will be affected least
Why is the alpha radiation the weakest?
Alpha radiation is not necessarily the "weakest" radiation. Alpha radiation is the emmanation of helium nuclei, which is two protons and two neutrons. As such, an alpha particle has a mass of 4 and a charge of +2. As a result, it interacts more readily than any of the other forms of radiation. This means that alpha can be stopped with a few inches or air, or even with a sheet of paper. That does not mean, however, that alpha is the least dangerous - if it is ingested, such as into the lungs, it will be in close proximity to sensitive tissues, making it one of the most dangerous forms of radiation. Its penetrating power is certainly the least, but, "weakest", not by a long shot.
Is uva radiation the lowest?
UV-A contains the least radiation (or energy) and is therefore, the least harmful. UV-C contains the most amount of energy and is the most harmful.
Can radon gas cause migraine headaches?
No, exposure to radon gas, even a large amount, won't give you a headache. Radon is an inert or noble gas, and it is radioactive. Radon exposure is a bad thing as it is the second most common cause of lung cancer. But you won't be able to detect radon by any of your senses, and it will not directly cause you to be "sick" or for a "migrane" to appear. It will, after time, cause cancer because the radiation damage your lungs get from the long exposure. In the mean time, you won't feel a thing. At least not because of an exposure to radon gas.
What element is used to block out dangerous radiation?
Alpha Radiation ( α ) – Least penetration. Will be blocked by a single sheet of paper. Beta Radiation ( β ) – More penetration than alpha. Blocked by a few mms aluminium. Gamma Radiation ( µ ) – Strong penetration. Needs a least a few inches of lead to block.
what cells types are least sensitive to ionizing radiation damage?
Cells that do not have a nucleus
Which of the following cell types are at least sensitive to ionizing radiation damage?
Cells that are actively dividing are most sensitive to radiation damage.
Which of the following cell types are least sensitive to ionizing radiation damage?
cells that divide slowly
What part of your body is least sensitive to radiation?
Science has proved that the nervous system is the least sensitive to radiation. Blood forming organs like marrow are the most sensitive.
What are the least sensitive explosives?
What are the least sensitive explosives used by military
What is the least penetrating form of a reaction?
Alpha particles are the least penetrating form of radiation. However, that does not mean they are the least dangerous. Even though they can be stopped with only an inch or so of air, or even by our skin, if they are ingested and come into contact with sensitive body tissues, they can be dangerous, because they have the highest charge and the highest mass.
What cell types is least injured by radiation?
Cells with no nucleus. Radiation affects actively dividing cells most. Even cells that are not dividing but contain a nucleus can be affected because the radiation damages the DNA. A cell without a nucleus lacks DNA to be damaged and will be affected least
What kind of radiation is least harmful to humans?
External to the body, alpha is not dangerous because it is easily stopped by the skin, but it becomes dangerous if ingested because it can then access internal sensitive organs directly. For electromagnetic radiation, visible light and infra-red are the least damaging. Ultra-violet causes sunburn)
What type of radiation is the least ionizing?
Alpha radiation.

The point where the southern hemisphere has the least exposure to the sun is the Summer solstice.
What type of ionized radiation is the least penetrating?
Alpha radiation.
What point does the southern hemisphere have the least exposure to the sun?
The southern hemisphere has the least exposure to the sun during the winter solstice. A+ Answer: Summer
