Why does moving further away from gamma radiation make things less dangerous?

Radiation disperses out in all directions, unless it is focused. This is true for Light. So the further away from the source, the more dispersed is the intensity.
Another reason is that the further away, the radiation is absorbed by objects, even dust in the air. Thus the intensity is reduced even more.
Think of a candle shinning light and the light going out as a large bubble. The further out that bubble goes, the more it has to stretch. The volume of the bubble grows by the Radius to the 3rd power. So if you Double the distance (times 2), the intensity does not drop by 1/2 but by 1/8 ---or 2 raised to the power of 3.

What are the disadvantages of radiations?
Radioactive radiation, such as X-rays and gamma rays, is dangerous and can harm, and even kill living things.
Which type of radiation-alpha beta or gamma- is most dangerous to living things?
Ionizing radiation can be dangerous to living things, as it upsets the chemistry in living cells by breaking covalent bonds between atoms. Even if the radiation is not ionizing, such as in neutron flux, damage can be done there as well, due to activation processes that change the chemical identity of atoms.
What element is used to block out dangerous radiation?
Alpha Radiation ( α ) – Least penetration. Will be blocked by a single sheet of paper. Beta Radiation ( β ) – More penetration than alpha. Blocked by a few mms aluminium. Gamma Radiation ( µ ) – Strong penetration. Needs a least a few inches of lead to block.
What is the difference between living and non living things?
a none living things are not moving a living thigs is moving
What is the color of alpha radiation?
Alpha radiation does not have a colour. In order for something to have a colour, it must emit rays of visible light. Alpha radiation and light are two different things which have little to do with each other.
Why is ionizing radiation dangerous?
Ionizing radiation by definition is radiation with a high enough energy to remove electrons from their orbits. This is dangerous because it emits x-rays, damages tissue, can cause long term damage like cancer, and heats things up.
Why is alpha radiation more dangerous than beta rediation when the source of the radiation is inside the body?
Alpha radiation cannot get pass through our body as it cannot penetrate through things. Beta can penetrate through things better than alpha. So if alpha is inside our body then it cannot get outside our body and therefore it becomes dangerous.
What two things make microwaves more dangerous?
Defective door which allows leakage of radiation and unappropriate recipients.

What are some ways in which radioactive elements can be dangerous?
Radiation, even in small doses, can cause cancer in humans and other living things Alpha radiation is responsible for most of the damage of DNA in living cells
What rays are dangerous to living things?
Death rays. Most types of radiation is dangerous, even the UV that makes it though the atmosphere. However, a human body can cope with a level or incoming radiation. Higher energy rays, such as gamma and x-rays are much more damaging, but fortunately they do not penetrate the atmosphere very well.
What things are electromagnetic radiation emitting from?
Electromagnetic radiation is emitted from many different things. Some of the things that emit electromagnetic radiation are microwaves, x-rays and radios.
Are micro waves dangerous?
It's a controversial question. In my opinion, yes. Microwaves heat food through radiation, which not only denatures the proteins and scrambles the DNA of your food, but also leaves trace amounts of radiation behind. This is one of those things that's probably okay once in a while, but daily for the rest of your life is pretty dangerous. Many people think the radiation is so minute that it's harmless. My thinking is, if you can avoid radiation, no matter how minute, do so.
What things have radiation?

Can mesothelioma be cured?
Tumors cannot exactly be "cured." They can be surgically removed, but the cancer will remain. Things like chemotherapy and radiation can be used to further treat, and hopefully destroy, the illness.
Good things about radiation?
Chemo radiation kill cancer cells.
