travelers from high altitude.
Cosmic rays of the Sun and space collide against the molecules in the atmosphere, causing
damage to the particles and radiation that can be harmful to our health.
The new study, using Meteorological balloons and published in the journal of space time,
take some measurements of the radiation of the first of its kind at an altitude of more
than 26,000 120,000 feet above the Earth.
While we especially believe this radiation in the ground, the pilots and aircrew are
exposed to harmful radiation, as astronauts.
To carry out the study, called ' The NASA radiation dosimetry experiment ', or RaD-X,
researchers launched balloons containing large helium into the stratosphere from near Fort
Sumner, New Mexico by 2015.
The balloon contains instruments to measure cosmic radiation from the Sun and interstellar
space.
The results, published in the daily time, take some measurements of the radiation of the
first of its kind at an altitude of more than 26,000 120,000 feet above the Earth.
They found a steady increase in the level of radiation in the atmosphere.
Magnetopshere the Earth acts as a magnetic shield and blocks most of the radiation from
reaching the planet.
But the particles with enough energy can penetrate the magnetosphere and atmosphere.
They collide with oxygen and nitrogen molecules, causing the particle radiation in
different particles through a process called nucleonic and electromagnetic Cascades.
Radiation in the atmosphere can be measured in two ways: there are many or how can
damage the biological tissue.
Measure damage to biological tissue, called "energy", is the standard way to measure health
risks and is much easier to measure than quantity of radiation.
This is because the level with the amount of radiation required to find out the type and
energy of the particles not only how many there are.
The main particles of high energy particles and secondary caries in can have a negative
effect on human beings.
This is because the cosmic DNA decomposes and produces free radicals, which can alter
cellular functions.
Dr. Chris Mertens, principal researcher from the Mission of RaD-X at NASA Langley
Research Center in Hampton, Virginia, said: ', for the first time, the steps taken in the seven
range of altitude, where the physics of dosimetry is very different.
' Have the measurements in these seven altitudes that we're not really able to prove what
our models as well as capture the physics of cosmic radiation '.
The researchers measured the level of equivalent dose of radiation in a variety of heights,
found a steady increase in the higher levels in the atmosphere.
The basic cosmic ray particles above more harmful to humans than the secondary particles.
The research has important implications for aircrew in the aviation industry, as you are
exposed to almost double the level of radiation from the people on the ground.
It is also a concern for international team riding a space station and future astronauts
traveling to Mars, who has environmental radiation similar to Earth's upper atmosphere.
Researchers say that learning how to protect people from radiation exposure is a key step
in the future of space exploration.
The results of the study can also be RaD X used to enhance a model of space time including
NAIRA, which predicts events of radiation.
This estimate is used by the pilot to control the levels of radiation and know when and
where the safe level so that they can adjust their routes.
While flying in a hot air balloon as a RaD-X is important for modeling environmental
radiation, does not provide real-time radiation monitoring NAIRA which requires foresight.
Automatic measurement of the radiation safety program for the NASA aerospace works in
conjunction with the RaD-X to develop and test an instrument that could be flown
commercial planes to monitor in real time at altitude.
A tool called TEPC-network equivalent proportional counter-standard instruments to
measure cosmic radiation, but large, expensive and could not be built commercially, by what
cannot be easily distributed.
' We need an instrument based on the country's dense, compact and small calibrated
against a reliable TEPC can measure the dose equivalent and can be integrated into the
aircraft that are inexpensive and compact, ' said Dr. Mertens.
Mission has tested two new instruments
