Are alpha particles harmful from a distance?
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).
How far do nuclear particles penetrate into human tissue?
The ability of particulate radiation to penetrate human tissue varies by particle type, and to some degree on the energy of the particle. The three basic types of particulate radiation are the alpha particle, the beta particle and the neutron. Let's look at them. The alpha particle won't penetrate very far at all. As the alpha particle is a helium-4 nucleus, it is massive, and it will be stopped by the outer most layers of the skin. As for beta particles, which are electrons or positrons, they can't go much farther. They'll be stopped before much penetration into the skin. That leaves just one other particle: the neutron. Neutrons have an extreme ability to penetrate tissue. They can do some serious damage, and we don't want to be on the receiving end of them. There are some other particle types, but they aren't generally seen outside the physics lab. These are the "big three" types of particulate radiation, you'll find links below to help you discover more.
What objective lens shows greatest depth?
The scanning electron microscope (SEM) has the greatest depth of field compared to other objective lenses in optical microscopes. This is because the SEM uses a focused beam of electrons to create an image, allowing for a larger range of depths to be in focus simultaneously.
Where would you expect to find photosynthetic organisms at the greatest depth and why?
You would expect to find photosynthetic organisms at the greatest depth in the euphotic zone of the ocean. This is because sunlight can penetrate to this depth, providing the necessary energy for photosynthesis. Beyond the euphotic zone, light levels decrease rapidly, making it difficult for photosynthetic organisms to survive and carry out photosynthesis.
How deep a sub surface void will show up in magnetic particle inspection?
The depth at which a subsurface void will show up in magnetic particle inspection depends on various factors such as the size and shape of the void, the strength of the magnetic field applied, and the sensitivity of the inspection equipment. In general, magnetic particle inspection is most effective for detecting flaws located near the surface or within a few millimeters below the surface.
How would you list alpha partcles beta particles and gamma rays in order of increasing penetrating power?
Alpha particles are the least penetrating, and are not able to pass through a single sheet of paper. Beta particles can penetrate through a sheet of paper, but not a piece of aluminum. Gamma rays can travel through both paper and aluminum and it takes dense material like lead to stop them or reduce their number. Gamma rays are high energy electromagnetic rays.

What is the penetrating power of infrared rays?
Infrared rays have a moderate penetrating power, able to reach the skin and tissues beneath the surface. They are commonly used for therapeutic applications such as pain relief and promoting healing due to their ability to penetrate the body to a certain depth.
