• Description:
  Modern real-time radiation dosimeters translate ionizing radiation, a physical entity, into an electrical charge using a variety of technologies. They are calibrated using well-established biological models of radiation-induced health effects and display dose-rate rather than exposure-rate. The newly developed Naphthalene Dosimeter is the first real-time chemical dosimeter. The technology is wearable, measures naphthalene air concentrations with laboratory quality. Miniaturization of deep UV light emitting diodes and photo-detectors are among the technological advancements that enable development of the naphthalene dosimeter. Independent laboratory validation experiments determined that the dosimeter is capable of meeting NIOSH standards for direct-read instrument over a range of naphthalene in air from 0.005 to 120 parts per million. In field validation studies involving military fuel handlers, prototype naphthalene dosimeters have detected individual exposures over the low end of this range, with concentrations being measured every three minutes. Compared to conventional methods for monitoring chemicals in the workplace, the naphthalene dosimeter also delivers increased precision in measurement of exposure rate and location. As data accumulate, PBPK models will be used to generate dosimetrics that when applied, will increase the reliability of naphthalene health risk assessments. In this regard, the naphthalene dosimeter is on the leading edge of real-time chemical monitors that will deliver more reliable risk assessments, real-time health protection, and improved sustainability, all at lower cost.
