The absorption of radiation is different for each shielding material and type of radiation.
There are many different kinds of radiation and the appropriate safety precautions are different for the different kinds. The precautions for using microwave radiation, for example are very different from the precautions for using gamma radiation, or infra red radiation.
If you are interested in taking a couple courses on radiation therapy, then there are many different kinds of schools that offer different courses in radiation therapy.
Some safety precautions when using radiation include wearing proper protective gear such as lead aprons and gloves, minimizing exposure time, maintaining a safe distance from radiation sources, and following proper protocols for handling and disposing of radioactive materials. Regular monitoring of radiation levels and receiving extensive training in radiation safety are also essential precautions.
There are lots of different kinds; you'd need to be more specific.
Shielding involves putting layers of material around a radioactive source (or around something which must be protected from radiation in general) to prevent radiation passing out of or into it. Shielding normally consists of extremely thick layers of concrete, and sometimes a thinner layer of lead. The concrete is often metres or tens of metres thick; lead is normally only decimetres or metres thick, as it is much more absorbent of radiation. shielding is generally used around a nuclear reactor to protect outside people or nature from radioactive radiations and even making inside reaction safe from alpha, beta and gamma from outside. Different nuclear emissions require different kinds of shielding. Of course, thickness can be important, so the thicker the better. Alpha particles do not penetrate well, so almost anything shields fairly well, even a piece of paper. Beta particles are a more difficult problem; they are shielded by objects of low density. A piece of aluminum will do for less energetic particles - wood or plastic will usually do for more energetic ones. Gamma rays (and X-rays, which are not nuclear radiation, but are ionizing) are best shielded by dense, heavy materials, such as lead. A thick layer of concrete is also good. Neutrons go through almost anything, but they bounce around when they hit the nuclei of atoms. They can also be absorbed by the atoms. Water moderates them, or slows them down, making them less energetic, fairly quickly. Since concrete is full of water, a few feet of it - or even earth - is a good shield. The other ionizing radiation, which is not nuclear, is ultraviolet light, which is easily shielded with UV blocks and screens.
· Alpha - a helium nucleus · Beta - a high speed electron · Gamma - an electromagnetic radiation of wavelength about 10-14 m.
There is only one kind. Although heat can be transmitted through radiation or contact or convection.

There are four types of VADs, each appropriate for a different condition.
Not necessarily. Different kinds of radiation detectors pick up different kinds of radiation. Also some radiation is of so little importance, that detectors are not designed to pick it up. An example here is UV light, which is actually low level ionizing radiation. One more thing: Radiation doesn't require air to travel. A quick example: The sun's radiation reaches earth, yet there is no air in space for it to travel through.
Height and speed are two entirely different kinds of things. There is no appropriate conversion.
Radiation is detected using instruments such as Geiger-Muller counters, scintillation detectors, and ionization chambers. These instruments are designed to measure the levels of radioactivity in a given area or object.
