safety and risks of radiation exposure due to aircraft

Is not just Roentgen! Daily radiation exposure

As for the international line those where time is long are problem!

Radiation the people who are worried about that it is bombed are not few in Roentgen and CT inspection, but to tell the truth we pour the radiation of the natural world daily.When you divide with the route which enters to the human body, there are some which are poured directly from the air and the food.The amount which is poured directly are those from the soil and those from outer space.Amount from the air, the food and the soil something by the radioisotope which puts out radiation is.Amount from the air is something by radon.

When those which have familiarity at amount from the food are listed there is a radioisotope of the kalium and a radioisotope of carbon.The isotope of carbon is used for the age determination of archaeology.

It falls from outer space, the earth when two protections (you call to the shooting game wind, the seal) has vis-a-vis “the cosmic ray”.

One with the seal due to terrestrial magnetism, in the South Pole and the North Pole becomes weak.When expression is changed, when latitude rises, the radiation due to the cosmic ray becomes strong.In the arctic circle as for the aurora being visible it is because of this.

Already one is the atmosphere (the air).The cosmic ray becomes weak when it strikes to the atmosphere, spreading.aircraft ground1ten thousandmshielded by the atmosphere becomes so weak fly more than, will be exposed to radiation due to cosmic rays more than the ground.

cosmic rays reach the earth, so very small amounts, need to worry about the impact on the human body there is no. being concerned about the effects of radiation of the natural world, if you would long plane ride.

cosmic-ray exposure of the ground plane is international10~100double

natural radiation from the air is not often!

units used by the radiation damage because it is difficult, i will describe here without using the unit.

usually, 1the amount of radiation that bathed in the year, let’s take a closer look at natural radiation. of natural radiation1from the air and about on a daily basis to estimate a year’s worth180days, about food60days, from the soil about60days, about cosmic rays60number of days will be sun-minute. minutes from the cosmic ray1/6so to make it easier to compute6the calculated in multiples of.

from narita to new york, one way12time, round-trip24time (1day) if you have been riding on the aircraft, on the ground6assuming that you have exposed to radiation from cosmic rays times the, 1will be exposed to radiation calculation of extra days of. 60and to calculate the times10will be irradiated days of.

60if times were calculated, years in new york businessman make frequent business trips abroad temporarily36when times were, of civilians in just the round-trip business trip1calculation that would be bathed in the same amount of years’ worth of natural radiation. given years of human2will be exposed to radiation of the times. but, this is a calculation of if you were in the air, not in the calculation of the amount of exposure in the aircraft. measurement and simulation by using a semiconductor measuring equipment, in the plane, exposure is less than the amount of calculation here.

the relationship between biodiversity and natural radiation

at the time of the birth of life on earth, there were natural radiation. life could not bear to natural radiation is extinct. life on earth has been followed so far, is the only living creatures to a certain amount of natural radiation is not a problem.

harm caused by radiation are concerned about, that occurs when radiation hits the molecules in the cell active oxygen is due to. i active oxygen is to oxidize the molecules in the cell, if you can not go back to the original molecule after it has been oxidized will not be able to have the original chemical reaction within the cell. you may also damage the genetic information. cells and a mechanism to clear the active oxygen, have a mechanism to repair the damaged genetic information.

radiation is not necessarily come to hear a little like boxing body blow. if i took a small amount of radiation, failure does not accumulate, will recover in a certain period of time up to the time of the radiation was not exposed to. in fact100drew together as a day’s worth of radiation, there is no big problem if.

but, if you drew a large amount of radiation at the same time as boxing uppercut, as this will kill cells. when cells die in the bone marrow, for example, can not stop bleeding such as nosebleeds by reducing the platelet, the debugger will not work and infectious diseases has decreased leukocyte. in the skin or hair missing, radiation damage that will occur or gastrointestinal tract perforation. in radiation damage is, the usual case, in the aircraft, exposure to large amounts of radiation at that level there is no first. excessive worry is unnecessary.

overseas travel during pregnancy, radiation exposure is safe?

during pregnancy, it is time to tend to be nervous, especially against radiation exposure. seem surprising, but is likely to be, malignant tumor and may be subject to radiation therapy, the fetus is in the stomach because there is a similar portion.

the human body against radiation-induced production of reactive oxygen species, the mechanism works to clear the active oxygen, if the fetus of maternal early on in the cell division, are considered because there is a possibility of gene repair mechanism can not keep up.

because there is no absolute safety, if you find out that you know is only pregnant for a long time i get on the aircraft might be avoided. although it is considered in most cases there is no problem at all, rather than for medical reasons, from the viewpoint of physics the universe can not be predicted, is because there is if there is a risk.

solar activity will change! also be very high because in rare cases, if you do not want to travel abroad are conservatively increase the unnecessary worry

physics point of view the universe, it is called, is the change in solar activity. this is the amount of cosmic rays is varied.

cosmic rays, sources to those of the sun, sources other than those of the sun2it can be divided into two, the latter unless they’re of a supernova explosion, that no significant variation. on the other hand, to cosmic rays from the sun there is a change.

the stochastic is very low it, there is a very large period of cosmic rays from the sun. if there is a possibility that would taking a large amount of radiation in a time of flight. to normal adult level but there is no problem to say that a large amount, if pregnant women are also useless because it does not increase the risk of, if unavoidable, we recommend that you avoid the aircraft except.

impact of airplane pilots and crew?

actual, if it is about to use the aircraft in a business trip or travel abroad, need to worry about the radiation is not. it might be a problem would be people working in aircraft. radiation exposure in aircraft it is certainly more than the ground.

not only time-of-flight, radiation due to cosmic ray exposure by route changes. shielded by the geomagnetic field in relation to, radiation due to cosmic rays near the equator is less, it increases as the higher latitude. many routes towards europe ‘s route from japan, on route towards southeast asia will be less. if the crew of the international, you should have double the number of people exposed to radiation common. for long-term effects, there is no detailed survey results still, is the consideration stage has begun, to come to a conclusion is likely to still take a long time.
