How does the gamma ray effect the body?
The body radiates energy through thermal conduction through the skin to the air, clothes, etc, around the body. A small amount of energy would also be radiated as electromagnetic radiation with a peak wavelength directly related to the Kelvin temperature of the skin. Also, very small amounts of other types of radiation are emitted due to naturally occurring radioactive isotopes in the body (i.e. Carbon-14).
Can a radioactive object make another object radioactive when it touches it?
Mostly no, but it depends on the nature of the two objects. Radioactive objects are usually emitters of alpha particles (helium nuclei), beta particles (electrons), and/or gamma rays (high-energy photons). None of those will usually induce secondary radioactivity in other objects. However, if neutrons are emitted, they can often penetrate the nuclei in another object, and if successfully absorbed there, can produce an unstable (radioactive) isotope. Also, if the source radioactive object is producing radon gas as a decay product, that can also be absorbed by some materials and start generating radiation there. (This does not require that it be "touching".)
When were microwaves radioactive?
Never, but it is considered a form of radiation in the loosest sense. It is not radioactive like Uranium or Plutonium, which give off radiation in the form of gamma rays or subatomic particles. X rays, radio waves, radar, microwaves, and visible light are all forms of electromagnetic "radiation". Whether these waves are harmful, and what uses they may be put to, if simple a function of their wavelength and intensity.
Gamma rays is more energetic when emits alpha or beta?
false
Why does lead block radioactivity?
Lead is applied as shielding to block (attenuate is the word we prefer) gamma rays. This form of radiation is electromagnetic in nature, and not particulate (composed of particles). Materials of high density (and lead is fairly high) are better at attenuating gamma rays than less dense materials. Additionally, lead is cheap and easy to work with. You've doubtless heard of lead being used to shield against X-rays, which are just a bit lower in frequency than the gamma rays.It is the "close spacing" of the atoms and the "bigness" of the atomic nuclei of lead that make it good for use in gamma ray shielding. Gamma rays "cut right through" electron clouds around atoms, and only the nuclei of atoms really give the gamma ray something to interact with. As regards particles, lead will stop alpha and beta radiation with ease, but so will a sheet of aluminum foil. Lead isn't that great at stopping neutron radiation. Shielding for neutrons requires atoms with small nuclei, so lead isn't so hot in that application.
When food is irradiated with gamma rays from a cobalt-60 source does the food become radioactive?
No. Gamma rays will not make materials radioactive.
What properties of radioactive isotopes make them usefull?
Radiation through alfa, beta & gamma decay.
Can gamma rays make a human being much powerful like the incredible HULK?
No, exposure to gamma rays will not give a person superhuman strength or turn them into the Hulk. In reality, exposure to gamma rays is extremely dangerous and can cause serious health issues such as radiation sickness, cancer, and even death. The Hulk is a fictional character created by Marvel Comics.
Does internal radiation therapy make people radioactive?
Patients receiving internal radiation therapy do become temporarily radioactive
What changes in a radioactive material to make it emit radiation?
Radioactive decay occurs when unstable atomic nuclei lose energy to become more stable. This process can involve emitting particles (such as alpha or beta particles) or electromagnetic radiation (such as gamma rays).
Would exposure to something which is radioactive make you radioactive?
Not much. There are various forms of radioactivity. A material can emit alpha particles, beta particles (high energy electrons), neutrons, gamma rays (high energy photos), or you can ingest it. If you eat, breathe or inject a radioactive material, it will be inside you and you will become "radioactive" in that you will emit particles or radiation. This is how PET works - the doctor injects a short-lived isotope and tracks the positrons emitted by them with a detector, so can track, say, the uptake of glucose in your brain. If you sit on a lump of radioactive material, the radiation will damage your skin and body to an extent depending on the intensity and type of radiation. If an emitted particle changes an atom in your body to an unstable isotope, this will later decay by emitting a particle itself. In this sense you will have been made "radioactive". This is I believe very unlikely - the side effects of radiation damage would kill you long before you had become significantly radioactive just from contact. A particle is more likely to break chemical bonds and create free radicals than to create a new isotope.
A radioative substance can make another object radioactive this is similar to?
transferring a virus to another person by means of a sneeze

How can radioactive contamination occur?
Radioactive contamination is also known as radiological contamination. It is the deposition, or presence of radioactive substances on surfaces within solids, liquids, or gases. There presence is unintended or undesirable.
What does darmstadtium make?
By radioactive decay of Ds other radioactive isotopes are appearing.
Why do you find all three alpha beta and gamma in many radioactive elements?
Because many radioactive elements undergo what is called a decay chain, or multiple decays until they finally become stable. For instance Thorium-232 undergoes a number of alpha and beta decays until it finally becomes stable as Lead-208. As such, while a compound may contain mostly Thorium-232, there may be a minute amount of other particles resulting from the decay of Thorium-232 producing different radioactive particles from Thorium-232. Another reason could be that certain radioactive particles can undergo more than one type of decay. For instance, Bi-213 can undergo either alpha or beta decay, and thus a sample of Bi-213 would emit both particles. Lastly, any particle that undergoes gamma decay will eventually undergo some other type of radioactive decay, since gamma ray emission does not actually change the atomic # of the element and thus does not make it eternally stable. Thus compounds producing gamma rays will always produce some other type of radiation as well, for instance Cobalt-60 produces gamma rays and beta particles
How does something become radioactive?
An element becomes radioactive when its nucleus is unstable and undergoes radioactive decay, emitting radiation in the form of alpha, beta, or gamma particles. This process occurs naturally for some elements or can be induced through nuclear reactions in a laboratory setting.
