What is the safe level of nuclear radiation?
The answer to the question depends more on what you consider safe than anything else. The real question is whether any given exposure has sufficient benefit to outweigh the amount of damage that might be done. In some cases, we need to do things that expose us to ionizing radiation in order to stay alive and be healthy, and the amount of exposure is so small that the chance of problems coming from it is to small to worry about. Any exposure to ionizing radiation can cause medical problems. There is no lower limit, beyond which it is absolutely safe. This includes not only nuclear radiation but other ionizing radiation, such as ultraviolet light, as well. For example, exposure to sunlight can cause skin cancer, and the chance of getting cancer is directly related to the amount of sunlight. The only way to eliminate the chance of getting cancer from sunlight absolutely is to eliminate the exposure absolutely. The problem with this is that we need some exposure to sunlight to ensure good health, so eliminating it is more dangerous than limited exposure. Similarly, exposure to beta or gamma radiation can cause medical problems, and the only way to eliminate these problems being caused by such radiation is to eliminate the exposure. The problem with eliminating the exposure is that it cannot be done. About one out of every 9000 potassium atoms is radioactive, and will give off gamma or beta radiation. But potassium is also a requirement for life, as a chemical, and eliminating it would quickly cause a person to sicken and die. We put smoke detectors in our houses, because early detection of fires saves lives. The smoke detectors usually contain radioactive substances, but the increased threat from them is negligible compared to the increased threat from fire without them. We are exposed to nuclear radiation in medical practice that is intended to benefit our health and extend our lives. So to answer the question precisely, we would have to say that there is no absolutely safe level of radiation greater than none at all. What we have to do is assess each potential source of radiation and ask whether the risk of exposure is small enough that the actual exposure is overall beneficial. Since the question of whether something is safe cannot be answered without some subjective evaluation, I will tell you my own belief. I believe that we are all subjected to as much radiation as we need, and probably more, already, assuming we use sunscreen or cover ourselves well. If any further exposure is to be done, there should be some very good, specific reason for it. So, the safe limit for further exposure is zero.
What is the formula t calculate acceleration?
The formula to calculate acceleration is: acceleration = (final velocity - initial velocity) / time.
How do you Calculate the frequency of 337.1 wavelength of nitrogen laser wave lengths of electromagnetic radiation?
To calculate the frequency of electromagnetic radiation, you can use the formula: frequency = speed of light / wavelength. Given the wavelength of 337.1 nm, first convert it to meters (337.1 nm = 337.1 x 10^-9 meters) and then plug it into the formula along with the speed of light (3.00 x 10^8 m/s) to calculate the frequency in hertz.
What is the formula to calculate the kinetic energy of a dumbbell in motion?
The formula to calculate the kinetic energy of a dumbbell in motion is: KE 0.5 mass velocity2.
What is the formula to calculate the net acceleration of an object?
The formula to calculate the net acceleration of an object is: Net Acceleration (Final Velocity - Initial Velocity) / Time.
What causes color in silicate minerals?
The color is derived from the elements in the mineral that accompany the silicon and oxygen in their chemical formula, their exposure to radiation, or the possible inclusion of trace elements or minerals.
What is the formula to calculate the period of a wave?
you find the formula... then you calculate it. Its that simple.
What does E.I. stand for in photography?
EI is the exposure index. (Also known as EV: Exposure Value) It is a number gained from a formula combining the values of the aperture width and shutter speed to calculate the amount of light reaching the film/sensor. DanW.
If the formula to calculate work is distance divided by time how do you apply the formula?
You would have a very tough time, because that isn't the formula to calculate work. (distance) divided by (time) is the formula to calculate speed. The formula to calculate work is: (force) multiplied by (distance).
