What is one characteristic of hard radiation?

It has long wavelengths
It is suitable for diagnostic radiology
It is ineffective at penetrating tissues
It emits fewer ions

The correct answer is: It is suitable for diagnostic radiology

Hard radiation is characterized by its ability to penetrate tissues effectively, which makes it suitable for diagnostic radiology. This type of radiation typically includes X-rays and gamma rays, which have high energy and short wavelengths compared to soft radiation. The penetrating ability of hard radiation is essential in medical imaging because it allows for the visualization of structures within the body, providing valuable information for diagnosis and treatment planning. In contrast, options highlighting long wavelengths, ineffectiveness at penetrating tissues, or emitting fewer ions do not accurately represent the properties of hard radiation. Long wavelengths pertain to soft radiation, which is less penetrating, while the statement about ineffectiveness in penetrating tissues contradicts the fundamental strength of hard radiation. Lastly, fewer ions emitted pertains to the ionization capabilities of radiation types, where hard radiation actually tends to produce more ions as it interacts with matter.
