In technology, radio waves or microwaves are typically used.In our day-to-day communication (WITHOUT technology), we also use visible light.
You could conceivably used any type of radiation to identify substances however the most commonly used ones are the Ultra-violet as they produce fluorescence in the visible range.
Visible light is an example of electromagnetic energy or radiated energy.
Microwaves radiation can only travel up to a few centimeters. This type of electromagnetic radiation is commonly used in microwave ovens, where it heats and cooks food by penetrating only the outer few centimeters.
Clarify the question. Are you refering to electromagnetic radiation in the spectrum commonly known as x-rays or to some other phenomenon, person, character etc.?
Ultraviolet (UV) radiation is commonly used to treat waste water. UV radiation in the germicidal range (between 200-300 nanometers) is effective in destroying harmful microorganisms present in the water. This process helps to disinfect the waste water before it is released into the environment.

The fastest that an electromagnetic wave can travel is 299,792,458 meters per second.That's the "speed of light" ... and all other electromagnetic radiation ... in vacuum.
By the oscillation wave energy of sub atomic 'particles' (the most commonly accepted form of such a particle being a 'wave bundle').

Lead is usually used because of its density and ability to block electromagnetic radiation.

Very simple: IR Radiation.

It is used to measure radiation and is commonly used to detect objects that produce nuclear radiation.

An X-ray (or Röntgen ray) is a form of electromagnetic radiation with a wavelength in the range of 10 to 0.01 nanometers, corresponding to frequencies in the range 30 PHz to 30 EHz. X-rays are primarily used for diagnostic radiography and crystallography. X-rays are a form of ionizing radiation and as such can be dangerous. In many languages it is called Röntgen radiation after one of the first investigators of the X-rays, Wilhelm Conrad Röntgen
