No, alpha particles do not present a hazard at a distance. Let's look at what's going on.
Alpha particles are composed of two protons and two neutrons. They are really the nuclei of helium-4, and they can have considerable kinetic energy when released from the nucleus of an unstable atom. But because they alpha particle is charged (a plus 2 owing to the presence of the pair of protons), and because it has a fair amount of mass associated with it, the alpha particle will "run into" atoms in air. This will cause the alpha particle to loose energy quickly, and it will end up capturing a pair of electrons after moving only a few meters (at most) in the air. There are links below to associated questions (where this issue has already been addressed).

Radioactive particle that is harmful to human beings?
Radioactive particles include alpha beta and positron they are not so harmful for human body the actually harmful are gamma radiations associated with these particles.
Why do alpha particles travel shorter distance in air than beta particles?
because alfa particle have a tendency to move in air then beta particles
Where could one locate Alpha particles?
Alpha particles are most commonly found when alpha decay occurs. An alpha particle is emitted during alpha decay. Further information about alpha particles can be found on the Wikipedia website.
Why does it take stronger magnetic fields to move the beam of alpha particles compared to beta particles?
Because the charge on an alpha particle is 2 times stonger then on a beta particle, however, it the alpha particle is 7,350 times more massive (so it takes more force to move it the same distance).
Do the alpha particles in Rutherford's experiment contain electrons?
Alpha particles are helium-4 nuclei; they do not contain electrons.
Which is the MOST harmful to the human body delivered from the same distance?
Alpha Particles

How do you check for harmful radiation levels?
You use a device called a Geiger Counter, which senses alpha and beta particles.
What are the harmful rays radiated from uranium?
Principally alpha particles, but also gamma rays, neutrons from the spontaneous fission, etc.
What effect does humidity have on alpha particles?
Alpha particles can be absorbed by water.

What gives off alpha particles?
Alpha particles are a type of particle of radiation that is emmited by certain radioactive materials. The materials that give off Alpha particles are called ''Alpha emitters.''
Which type of radiation is easiest to shield?
The type of radiation that is easiest to shield are alpha particles. They are also the least harmful. Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus.

Name the nuclear radiation that can be easily stopped by skin or cloths?
alpha particles.
