AnswersDriveTime, distance, and shielding actions minimize your exposure to radiation in much the same way as they would to protect you against overexposure to the sun: Shielding: Barriers of lead, concrete, or water provide protection from penetrating gamma rays.
What materials can stop radiation?
Despite their ability to penetrate other materials, in general, neither gamma rays nor x-rays have the ability to make anything radioactive. Several feet of concrete or a few inches of dense material (such as lead) are able to block these types of radiation.
What materials reduce radiation?
Beta particles (electrons) are more penetrating, but still can be absorbed by a few millimeters of aluminum. However, in cases where high energy beta particles are emitted shielding must be accomplished with low atomic weight materials, e.g. plastic, wood, water, or acrylic glass (Plexiglas, Lucite).
1
What materials block radio waves most effectively?
Thin amounts of plastic wrap, wax paper, cotton and rubber are not likely to interfere with radio waves. However, aluminum foil, and other electrically conductive metals such as copper, can reflect and absorb the radio waves and consequently interferes with their transmission.

How do you decontaminate from radiation?
2b. Wash yourself off.
- Take a warm shower and gently wash yourself with lots of soap. Do not scald, scrub, or scratch your skin.
- Wash your hair with shampoo or soap.
- Keep cuts and abrasions covered when washing to keep from getting radioactive material in open wounds.
3
How can we prevent radiation?
Use Time Distance and Shielding to Protect Yourself. Putting distance and shielding between you and a radiation source is an immediately effective way of reducing your exposure. Reducing the time you are being exposed is another way. Use a Respirator or Face Mask if You are exposed to airborne sources.
4
How do you protect yourself from nuclear fallout?
Reduce exposure – Protect yourself from radioactive fallout with … shielding – heavy, dense materials (like thick walls, earth, concrete, bricks, water and books) between you and fallout is best. Stay indoors or below ground. (Taking shelter in a basement or a facility below ground reduces exposure by 90%.
5
What can stop a beta particle?
Alpha radiation consists of helium nuclei and is readily stopped by a sheet of paper. Beta radiation, consisting of electrons or positrons, is stopped by thin aluminum plate, but Gamma radiation requires shielding by dense material such as lead, steel or concrete.
6
What is EMF protection?
The foundation of effective EMF protection is measurement, avoidance and protection. It means minimizing your exposure to EMFs while simultaneously supporting your body with the raw materials it needs to protect and repair itself.
7
What is the equivalent to an alpha particle?
It consists of two neutrons and two protons, and is thus identical to the nucleus of a helium atom. The rest mass of the alpha particle amounts to 6.64424.
8
What is the radiation of beta?
Beta radiation is radiation due to beta particles, which are electrons (or, sometimes, positrons); mostly, when you come across the words 'beta radiation', what is meant is what is produced by beta decay (radioactive decay which produces beta particles … either electrons or positrons).

How do you protect yourself from cell phone radiation?
15 Ways To Protect Yourself From Your Cell Phone
- Keep your distance. Do not keep your cell phone next to your body or in your bra.
- Talk on speaker. Holding a cell phone to your ear also exposes your salivary glands to EMFs.
- Turn your phone off more often. No radiation is emitted when the device is off.
- Consider alternatives.
- Use an EMF shielding device.
10
How can you protect yourself from UV rays?
- Cover up. Wear tightly-woven clothing that blocks out light.
- Use sunscreen. A sun protection factor (SPF) of at least 15 blocks 93 percent of UV rays.
- Wear a hat. A wide brim hat (not a baseball cap) is ideal because it protects the neck, ears, eyes, forehead, nose, and scalp.
- Wear UV-absorbent shades.
- Limit exposure.
11
What can stop beta radiation?
Alpha particles can be stopped by a sheet of paper, beta particles by aluminum, and gamma radiation by a block of lead.
12
How does gamma decay differ from both alpha decay and beta decay?
Difference between Alpha, Beta and Gamma radioactive decay can be summarized as follows: Alpha decay forms new element with two fewer protons and two fewer neutrons; Gamma decay forms NO new element, but now the element has less energy because energy is released as gamma rays.
13
What are some medical uses of radiation?
The most well known is using x rays to see whether bones are broken. The broad area of x-ray use is called radiology. Within radiology, we find more specialized areas like mammography, computerized tomography (CT), and nuclear medicine (the specialty where radioactive material is usually injected into the patient).
14
What process releases gamma rays?
It can then decay to a lower energy state by emitting a gamma ray photon, in a process called gamma decay. The emission of a gamma ray from an excited nucleus typically requires only 10−12 seconds. Gamma decay may also follow nuclear reactions such as neutron capture, nuclear fission, or nuclear fusion.

How far do gamma rays travel in air?
Gamma rays are bundles (quanta) of energy that have no charge or mass and can travel long distances through air (up to several hundred meters), body tissue, and other materials. A gamma ray is extremely penetrating and represents an external hazard.
17
How is gamma radiation used to treat cancer?
Gamma rays are mostly used in the radiotherapy/ radiooncology to treat cancer. They can also be used to spot tumours. Gamma rays can kill living cells and damage malignant tumor. They damage the cancerous cells' DNA, causing them to die or reproduce more slowly.
18
What can stop an alpha particle?
Alpha radiation consists of helium-4 nucleus and is readily stopped by a sheet of paper. Beta radiation, consisting of electrons, is halted by an aluminium plate. Gamma radiation is eventually absorbed as it penetrates a dense material. Lead is good at absorbing gamma radiation, due to its density.
19
How far do beta particles travel in air?
In air, beta particles can travel a few hundred times farther than alpha particles—up to six feet (two meters) or more for the beta particles with higher energies. For the common low-energy beta emitters used in laboratories, light clothing or a few centimeters of air can stop the beta radiation.

What is the charge of a beta particle?
| Type of Radiation | Alpha particle | Beta particle |
|---|---|---|

| Charge | +2 | -1 |
| Speed | slow | fast |
