Rationale:
- Diagnostic X-rays typically operate in the energy range of 10-150 keV (kiloelectron volts). This range is optimal for penetrating the human body and producing high-resolution images of internal structures such as bones and organs.
- X-rays within this energy range have sufficient energy to pass through soft tissues but are absorbed by denser materials like bone, allowing for clear contrast in diagnostic imaging.
Explanation of Other Options:
1-10 keV
- Rationale: X-rays in the 1-10 keV range do not have enough energy to penetrate the human body effectively. They are absorbed primarily by the skin and soft tissues, making them unsuitable for diagnostic imaging.
1-5 MeV
- Rationale: This energy range is much higher than what is used for diagnostic X-rays. X-rays in this range are used in therapeutic applications, such as radiation therapy for cancer treatment, as they can penetrate deeper tissues and deliver therapeutic doses to targeted areas.
1-10 MeV
- Rationale: Similar to the previous option, X-rays in the 1-10 MeV range are too energetic for diagnostic purposes and are used primarily in radiation therapy. They have a high penetration power, making them suitable for treating deep-seated tumors.
Conclusion:
- Among the given options, the 10-150 keV range is the typical energy range for diagnostic X-rays. This range is effective for producing clear and detailed images of the body's internal structures while minimizing radiation exposure to the patient.
