Insights

Workers face optical radiation exposure during infant phototherapy. Some devices pose retinal hazards from blue light and unnecessary UV exposure, necessitating safety measures for staff and infants.

Area of Science:

  • Medical Physics
  • Occupational Health
  • Neonatology

Background:

  • Phototherapy is a standard treatment for infant hyperbilirubinemia.
  • Understanding the safety of phototherapy devices is crucial for clinical practice.
  • Staff exposure to optical radiation during phototherapy is not well-characterized.

Purpose of the Study:

  • To assess occupational exposure to optical radiation from infant phototherapy devices in Italy.
  • To identify potential hazards associated with different phototherapy equipment.

Main Methods:

  • Evaluated spectral emissions from various phototherapy devices.
  • Measured operator proximity and duration of exposure during monitoring.
  • Assessed risks of photochemical retinal damage and UV exposure.

Main Results:

  • Significant variability in spectral emissions across devices.
  • Some equipment emits hazardous blue light and unnecessary UVA radiation.
  • Operators frequently work within 25 cm of radiation sources.

Conclusions:

  • Certain phototherapy devices pose optical radiation risks to operators and infants.
  • Protective measures, including eyewear and optimized equipment design, are recommended.
  • Clear safety standards for phototherapy lamps are needed.

Mutations01:35

Mutations

Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material,  molecules absorb light depending on the energy required for...

UV–Vis Spectrometers01:14

UV–Vis Spectrometers

The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell.
