Gamma rays have very short wavelenght and therefore have very high penetrating power. When gamma rays hit living cells, our cells cannot withstand such an high intensity radiation which results in apoptosis of the cell. The penetrating effect of gamma rays can be minimized by using thick sheets of lead around the gamma ray source.

Which is the most dangerous type of nuclear radiation if the source is outside the body?

Gamma radiation is the most dangerous type of nuclear radiation if the source is outside the body, as it can penetrate through the body causing damage to cells and DNA. It has the highest energy and can travel the farthest distances.


Gamma radiation is it safe to inject into a human but alpha particles would be very dangerous?

Generally no radiation is safe. You cannot "inject" radiation into anything because it is the product of various unstable nuclei decaying. Alpha radiation is much more ionising than gamma, but much less penetrating than it. That makes it more dangerous if it is inside your body; it can be stopped by skin. Therefore you would have to swallow a sample of a radioactive material. However, gamma radiation is always emitted together with alpha or beta radiation.


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.


Why does a kidney scanner use gamma radiation rather than beta or alpha radiation?

A kidney scanner uses gamma radiation because it has higher penetration ability, allowing it to reach and image deep structures inside the body like the kidneys. Beta and alpha radiation have lower penetration abilities and would not be suitable for this purpose. Additionally, gamma radiation is less likely to be absorbed by surrounding tissues, providing clearer images of the kidneys.


Why are gamma rays more dangerous outside the skin?

Gamma radiation can cause serious problems to the body. If you come in contact with high levels of radiation it can cause serious illness and death. Possible symptoms include nausea and vomiting, diarrhea, headache, fever, dizziness and disorientation, weakness, fatigue, hair loss, bloody vomit and stools, infections, poor wound healing and low blood pressure.

Is there more severe radiation than gamma?

It depends on the strength of the active source. Alpha radiation is dangerous if it gets inside your body, gamma will penetrate your clothing and body if energetic enough, so it's difficult to give an answer that covers all cases. Health physicists have to consider each type of radiation on its merits.


What type of radiation is probably the most dangerous to humans?

Externally, gamma radiation is dangerous because it can penetrate the body. Alpha is most dangerous if ingested.


What radiation is most dangerous outside the body?

the most dangerous radiation outside your body mostly consists of human disposal waste which smells. Arkenales and gamma are the most dangerous, and have a high percentage of harmful toxins.


Is gamma radiation the most dangerous kind of radiation?

Gamma radiation is considered among the most dangerous forms of radiation due to its ability to penetrate deeper into the body and cause damage to cells and DNA. However, the level of danger also depends on the dose and exposure time.

Explain why beta radiation can be used in treating skin cancer but not cancer inside the body?

Beta radiation isn't used for cancer inside the body because it doesn't have the penetrative ability of Gamma radiation. Gamma cannot be used for skin cancer because it would kill too many healthy cells.


What is more dangerous gamma or alpha rays?

alpha radiation is more dangerous than beta or gamma if ingested or inhaled because its power to ionize (or to disrupt atoms) is 20x than that of beta and gamma. but if the source is outside the body or at a distance gamma radiation is much dangerous because it could penetrate thick walls.


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.


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.


Why gamma rays cosidered the most dangerous EM?

Gamma rays are considered the most dangerous type of electromagnetic radiation because they have the highest energy and can penetrate deep into body tissues, causing damage to cells and DNA. In large doses, gamma rays can cause acute radiation sickness, cancer, and even death. Protection from gamma rays typically involves shielding with dense materials like lead or concrete.


What form of radiation can penetrate deeply into body tissue?

Gamma radiation, X Rays
