Mondo Health Updated on 2024-03-02

UV lamps, also known as ultraviolet lamps, especially short-wave ultraviolet (UVC) and some long-wave ultraviolet (UVB) lamps, have potential harm to the human body

Long-term or high-intensity exposure to ultraviolet rays may cause acute reactions such as sunburn, erythema, and peeling, and increase the risk of cancer, such as basal cell carcinoma, squamous cell carcinoma, and malignant melanoma.

Some people are sensitive to ultraviolet rays and may have an allergic reaction, such as photosensitive dermatitis.

Direct exposure to the eye can cause electro-optic ophthalmia or photoconjunctivitis, which manifests as eye pain, tearing, and photophobia. Long-term or repeated exposure to ultraviolet rays can also cause chronic eye diseases such as cataracts.

Long-term exposure to low-dose ultraviolet rays may suppress the function of the immune system and reduce the body's resistance to disease.

Therefore, it is essential to take appropriate precautions when using UV lamps for disinfection,** or other applications.

For example, wear UV protection goggles, wear covering** clothing, and make sure to use it in an unmanned environment or when not directly exposed.

At the same time, operators should follow safety guidelines and recommended working distances and time limits.
