Diagnostic Reference Levels and Other Metrics

diagnostic reference levels

Any individual who undergoes a medical imaging examination is subject to the benefits as well as the risks of the examination. Each individual is unique, with a unique body habitus, health status, and medical needs. Because of the wide variety and complexity of medical conditions, dose limits cannot be set for medical exposures. However, the average radiation exposure associated with a diagnostic or interventional procedure can be used to assess whether the dose received by the patient is within acceptable range. In other words, estimated exposure levels for different examinations help to highlight any substantial variation from the expected value. Certain metrics such as diagnostic reference levels make this possible.

Radiation Monitoring Devices for Healthcare Workers

radiation monitoring

Radiation is used in digital radiographic imaging departments to diagnose and treat a vast number of medical conditions. The benefits of radiation in diagnostic imaging are beyond dispute, but ionizing radiation can be harmful to the human body. For this reason, radiation monitoring devices are critical. A number of detection devices have been developed to calculate the radiation exposure received by an individual and to detect the amount of radiation present in the environment or on surfaces (contamination).

Occupational Radiation Dose Records: Why They Are Important

Occupational radiation dose records

In addition to the individual reporting of occupational doses, the conditions under which workers are exposed to radiation are also monitored with workplace records. Sometimes workplace records must be relied upon to estimate individual doses when a particular employee’s occupational radiation dose record is not available. Workplace records are useful in assessing the effectiveness of the radiation safety program at a facility.

Bone Biology Review: What Does New Research Show?

bone biology review

There is considerable scientific knowledge about the causes, prevention, and treatment of bone disorders, but many gaps remain in this information. For example, it is not clearly understood why fractures occur in so many people. In this bone biology review, we look at some of the recent discoveries in skeletal genetics and metabolism that are expected to improve our understanding of bone health.
