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).
What else can I help you with?
What factors will affect the extent of scattering of the alpha particles?
The factors that will affect the extent of scattering of alpha particles include the charge and mass of the nucleus they interact with, the impact parameter (closest approach distance), and the energy of the alpha particles. Additionally, the angle of deflection will be influenced by the velocity and direction of the alpha particles as they approach the nucleus.
What is an alpha particles and what stops them?
Alpha particles are positively charged particles consisting of two protons and two neutrons. They have low penetration ability and can be stopped by a piece of paper, clothing, or a few centimeters of air. However, they can be harmful if inhaled or ingested.
Radioactive particle that is harmful to human beings?
Plutonium-239 is a radioactive particle that is harmful to human beings due to its high toxicity and ability to emit high-energy alpha particles, which can damage cells and cause long-term health effects such as cancer and organ failure if ingested or inhaled.
What are alpha particles emitted by a microgram of plutonium over a year?
A microgram of plutonium emits approximately 2.2 million alpha particles per second. Over a year, this would amount to around 69 trillion alpha particles. Alpha particles are high-energy and can be harmful if ingested or inhaled, increasing the risk of cancer and other health issues.
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 is alpha radiation more harmful inside the body than outside it?
Alpha radiation is more harmful inside the body because alpha particles have a high ionizing power and are more likely to interact with cells and tissues, causing damage to DNA. When emitted outside the body, alpha particles can be stopped by skin or clothing and are less likely to penetrate deeply into tissues where they can cause harm.
Radioactive particle that is harmful to human beings?
Plutonium-239 is a radioactive particle that is harmful to human beings due to its high toxicity and ability to emit high-energy alpha particles, which can damage cells and cause long-term health effects such as cancer and organ failure if ingested or inhaled.
Would a layer of clothing protect alpha particles?
No, alpha particles have low penetration abilities and can be stopped by a layer of clothing or even a piece of paper. However, caution should still be taken with exposure to alpha emitters, as they can be harmful if inhaled or ingested.
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.

Why do alpha particles travel shorter distance in air than beta particles?
Alpha particles are larger and heavier than beta particles, so they interact more readily with air molecules through collisions. This causes alpha particles to lose their energy more quickly and travel shorter distances in air compared to beta particles, which are smaller and lighter. Additionally, alpha particles have a higher ionization potential, leading to more interactions with air molecules and a shorter range in air.
