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.

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 are the disadvantages of radiations?
Some disadvantages of radiation exposure include an increased risk of cancer, genetic mutations, and skin damage. Prolonged exposure to high levels of radiation can also lead to radiation sickness and potential long-term health complications.
Which type of radiation alpha beta and gamma is dangerous of living things and why?
Among alpha, beta, and gamma radiation, gamma radiation is generally considered the most dangerous to living things due to its high penetration power and ability to pass through human tissue. Alpha particles can be stopped by a sheet of paper and are primarily hazardous when ingested or inhaled, while beta particles can penetrate skin but are less damaging than gamma rays. Gamma radiation can cause significant cellular damage and increase the risk of cancer, making it particularly harmful in exposure scenarios. Overall, the danger of each type of radiation depends on factors such as exposure duration and the pathway of entry into the body.
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.
How does the absorption of ultraviolet radiation by the ozone layer help sustain life-?
The absorption of ultraviolet radiation by the ozone layer help to sustain life because it helps to protect living things from damage of solar radiation.
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.
Which types of EM radiation can be dangerous to living things?
Ionizing radiation, such as X-rays and gamma rays, can be dangerous to living things because they have enough energy to remove electrons from atoms, causing damage to cells and DNA. Ultraviolet radiation, particularly UVB and UVC, can also be harmful as they can cause sunburn, skin cancer, and other health issues with prolonged exposure.
Which type of radiation alpha beta or gamma is most dangerous to living thing?
Gamma radiation is generally considered the most dangerous to living things because it can penetrate deeply into tissue and cause cell damage throughout the body. Alpha and beta radiation are less penetrating and can be more easily shielded against.
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 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 two things make microwaves more dangerous?
Microwaves can be more dangerous due to the potential for thermal burns if food or containers get too hot, and the risk of exposure to radiation if the microwave door is damaged or the device is leaking electromagnetic waves.
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.
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.
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 are the disadvantages of radiations?
Some disadvantages of radiation exposure include an increased risk of cancer, genetic mutations, and skin damage. Prolonged exposure to high levels of radiation can also lead to radiation sickness and potential long-term health complications.
How was the donner party an American nightmare?
The Donner party proved how dangerous moving west in the United States could be, and how many things could go wrong.
