Staying inside will reduce your exposure to radiation.

• Close windows and doors.
• Take a shower or wipe exposed parts of your body with a damp cloth.
• Drink bottled water and eat food in sealed containers.

How-To Protect Yourself From Cell Phone Radiation

1. Use airplane mode as often as possible.
2. Do not sleep with your cell phone near you.
3. Keep the phone away from your body.
4. Keep the phone away from your head.
5. Avoid products that claim to block radio frequency energy.
6. Reduce cell phone use when the signal is weak.
7. Remove your headsets when not on a call.

It is postulated short- and long-term effects of CNS exposure to galactic cosmic radiation are likely to pose significant neurological health risks to human long-term space travel.

The Earth’s atmosphere and magnetic shield protect us from cosmic radiation. Earth’s magnetic shield protects us from the cosmic radiation and is strongest at the equator and weakest near the poles. The magnetic shield diverts most of the radiation around the earth.

Earth’s protective magnetic bubble, called the magnetosphere, deflects most solar particles. The atmosphere also quells any particles that do make it through. The International Space Station cruises through low-Earth orbit, within Earth’s protection, and the station’s hull helps shield crew members from radiation too.

They found that radiation levels on the Moon’s surface are 200- to 1,000-times more than that on Earth’s surface – and 2.6-times more than what astronauts onboard the International Space Station (ISS) are exposed to. The Chang’e 4 lander landed in the von Karman crater on the Moon’s far side on January 3, 2019.

By placing tons of engine assembly, cargo and fuel in between the astronauts and the very directional radiation source that is the sun, this should shield them effectively — though you’d need some emergency shelter on the Martian surface. The primary shielding material for the ISS is polyethylene (HDPE).

Radiation can be created by humans (microwaves, cell phones, radios, light bulbs, diagnostic medical applications such as x-rays) or naturally occurring (the Sun, radioactive elements in the Earth’s crust, radiation trapped in the Earth’s magnetic field, stars, and other astrophysical objects like quasars or galactic …

Actually, radio waves travel very quickly through space. Radio waves are a kind of electromagnetic radiation, and thus they move at the speed of light. The speed of light is a little less than 300,000 km per second. At that speed, a beam of light could go around the Earth at the equator more then 7 times in a second.

Space suits provide protection from the UV rays, but they provide limited protection from particle radiation and gamma and x ray. If particles have enough energy they simply pass through the space suit.

Radiation exposure induces various biological effects with the main effect being damage to DNA. There are various types of radiation-induced DNA damage, including base damage, single-strand breaks (SSBs), and double-strand breaks (DSBs) [70–73]. Among them, DNA DSBs are the most severe DNA lesion.

Radiation damages DNA and damaged DNA can lead to cancer, raising fears that astronauts and cosmonauts have an increased risk of cancer from their time spent in space. NASA lists “Risk of radiation carcinogenesis from space radiation” as one of its top research priorities.

Too Much Sun is Dangerous Sunlight, an essential prerequisite for life, may be extremely dangerous to human health. Excessive exposure to the sun is known to be associated with increased risks of various skin cancers, cataracts and other eye diseases, as well as accelerated skin ageing.

Radiation from the warmed upper atmosphere, along with a small amount from the Earth’s surface, radiates out to space. Most of the emitted longwave radiation warms the lower atmosphere, which in turn warms our planet’s surface.

Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness”). It can also result in long-term health effects such as cancer and cardiovascular disease.
