Summary
Comparing UVR detectors for skin cancer risk assessment, this study found that while common detectors accurately estimate non-melanoma skin cancer (NMSC) induction, they may be inadequate for melanoma risk due to differing action spectra.
Area of Science:
- Photobiology
- Dermatology
- Environmental Health
Background:
- Assessing human skin cancer risk from solar ultraviolet radiation (UVR) involves diverse methods for dose quantification, yet data comparability remains limited.
- Understanding the relationship between UVR dose and biological effect is crucial for accurate risk assessment.
Purpose of the Study:
- To compare the biological effectiveness of UVR detectors against established action spectra for skin cancer induction.
- To evaluate the influence of solar zenith angle, season, and latitude on UVR dose measurements.
- To determine the suitability of common UVR detectors for mimicking biological effects relevant to erythema, non-melanoma skin cancer (NMSC), and melanoma.
Main Methods:
- Calculated biologically weighted UVR effectivities using solar spectra from different latitudes and times.
- Convolved spectral data with CIE action spectra for erythema and NMSC, and ICNIRP's weighting function.
- Compared UVR detector responsivities with calculated biological effects and analyzed solar zenith angle dependencies.
Main Results:
- Solar zenith angle dependence showed similar patterns for CIE erythema and NMSC spectra, with minor seasonal/latitudinal influence.
- Setlow's action spectrum for melanoma induction exhibited a different solar zenith angle dependence.
- While UVR detectors showed discrepant absolute irradiances, correction factors largely independent of solar zenith angle related them to CIE spectra.
- Common detectors accurately estimate NMSC induction but may be inadequate for melanoma induction.
Conclusions:
- Commonly used UVR detectors can provide accurate estimates for non-melanoma skin cancer induction by solar UVR.
- These detectors may be inadequate for mimicking the biological effects relevant to melanoma induction.
- Further research is needed to develop or select detectors that accurately represent melanoma induction spectra.

2.0K
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.

16.5K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

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.

3.8K
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...

The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force...

2.9K
Atomic emission spectroscopy (AES) is an analytical technique used to determine the elemental composition of a sample by analyzing the light emitted from excited atoms. In AES, atoms in a sample are excited to higher energy levels by thermal energy from high-temperature sources, such as plasma, arcs, or sparks. When these excited atoms return to lower energy states, they emit light at specific wavelengths characteristic of each element. The resulting atomic emission spectrum, which consists of...
