What is actinic energy?

Why are UV rays called actinic rays?

Actinic is also used to describe medical conditions that are triggered by exposure to light, especially UV light (see actinic keratosis). The term actinic rays is used to refer to this phenomenon.

What does the word actinic keratosis mean?

Listen to pronunciation. (ak-TIH-nik KAYR-uh-TOH-sis) A thick, scaly patch of skin that may become cancer. It usually forms on areas exposed to the sun, such as the face, scalp, back of the hands, or chest.

Recreates light conditions found in deep water and provides the light energy necessary for proper photosynthetic coral growth. Actinic bulbs are ideal for reef aquariums.

Should actinic keratosis be removed?

An actinic keratosis sometimes disappears on its own but might return after more sun exposure. It’s hard to tell which actinic keratoses will develop into skin cancer, so they’re usually removed as a precaution.

Is infrared UV?

Light (also referred to in professional literature as radiation) is best thought of as a spectrum consisting of ultraviolet light (UV) at the short end, visible light in the center, and infrared (IR) wavelengths at the long end.

What does actinic radiation mean?

Medical Definition of actinic rays. : radiation (as in the violet and ultraviolet parts of the spectrum) having marked photochemical action.

What does actinic ray mean?

Actinic is also used to describe medical conditions that are triggered by exposure to light, especially UV light (see actinic keratosis ). The term actinic rays is used to refer to this phenomenon. In biology, “actinic light” denotes light from solar or other sources that can cause photochemical reactions such as photosynthesis in a species.

What does actinic rays mean?
