Gamma rays from ultra-high energy, we can find them on cosmic rays like galactic radiations, quasars, pulsars and so on, check this:

A radiating substance emits three types of radiadtions.
1. Alpha rays
2. Beta rays
3. Gamma rays
Of these three,
Alpha particles emitted by radioactive nuclei are among the most hazardous forms of radiation, if these nuclei are incorporated within a human body. As any heavy charged particle, alpha particles lose their energy within a very short distance in dense media, causing significant damage to surrounding biomolecules. On the other hand, external alpha irradiation is not harmful because alpha particles are completely absorbed by a very thin (micrometers) dead layer of skin as well as by a few centimeters of air. However, if a substance radiating alpha particles is ingested or inhaled by (or injected into) an organism it may become a risk, potentially inflicting very serious damage to the organisms' genetic makeup.
One example hazard is the gas Radon that can easily be inhaled and decay inside a human or animal lung, risking exposure of the lung tissue to alpha particles.

Gamma Radiations are the Most powerful type of radiations.They have the shortest wavelengths and are therefore highly penetrating.They are the type that are released from radioactive elements used in Nuclear Bombs.These radiations are even more penetrating than X-Rays,and can literally Cook you Alive.

If you are talking about the amount of Harm it can do then it has gotto be Alpha Radiation.And if you are talking about the Penetration Power then It is definately the Gamma Radiation.
In any case ,Radiation is a terribly Harmful thing to Play with.Therefore be Careful.
(Personally the most powerful Radioactive Element that i have known is "Plutonium".)

There are 3 possible forms of radiation come from a radioactive material, alpha radiation, beta and gamma radiation. alpha radiation is emitted when uranium-238 is disintegrated into thorium-234, beta radiation can come from radioactive plutonium and gamma radiation can come from radium. alpha and beta radiation are in form of particles for which alpha particle consist of 2 protron and 2 neutron, it's short ranged about 5-10cm, beta radiation is in form of an electron coming from the nucleus its range is about 0.5 m, gamma radiation is in form of a electromagnetic wave, it travels at the speed of light so it had very long range, in the aspect of energy, gamma wave is the most powerful radiation, in the aspect of being able to harm life, alpha particles are the most powerful, because gamma wave will just go through our body without any collision with our cells thus mutation caused by gamma wave is quite unlikely.

Cosmic radiation,In astrophysics, cosmic rays are radiation consisting of energetic particles originating beyond the Earth that impinge on the Earth's atmosphere. Cosmic rays are composed mainly of bare nuclei, roughly 87% protons, 12% alpha particles (helium nuclei) and most of the rest being made up of heavier atomic nuclei with relative abundances comparable to those found in the Sun. Electrons, gamma rays, and very high-energy neutrinos also make up a much smaller fraction of the cosmic radiation.

From an ionising perspective it would be alpha radiation. From a penetrating perspective it would be gamma radiation. The two types of beta radiation are roughly between alpha and gamma radiation. There is also neutron radiation which is particulary nasty for any living things and is very difficult to shield from.

Guys, Friends There are OTHER BEAMS THAN alpha, beta gamma,..
Radiation can be destructive when it has a high LET or Linear Energy Transfer i.e. capability to deposit energy over its tract inside the body,.. needless to say higher it is higher is the effectiveness or "power"
To put the kill-power in an ASCENDING ORDER:
x-ray < proton beam < Helium beam < pion beam < carbon < Neutron beam < neon beam < Silicon beam < Argon beam
As we can see x-ray WHICH IS SAME AS GAMMA RAY is way down in the list,.. pl also know that argon listed here is NOT argon laser but rather charged particle
