Is Ultraviolet Energy Carcinogenic?

The answer to that question depends upon one not making a broad generalization. One must first describe what type ultraviolet is being referred to. Basically the UV spectrum is divided into 3 types, A ( 350 nm ) - B ( 300 nm) - C ( 250 nm) rays.

The first two types, A + B, have been proven to be carcinogenic in that with extended exposure the cumulative effect can be to create a carcinogenic response. On UV-C, the null hypothesis was established when the researchers tried to create a carcinogenic response. UV-C is not a carcinogenic agent.

A sure give away when one looks at acquiring UV equipment for wound care is to look at the treatment protocol. If the unit promoted has descriptions of treatment such as extending the treatment time each day or application that is generally a give away that the unit is not a lamp emitting C range but either A or B range. This type unit is not FDA approved, nor warranted for use as a wound lamp. The reason for the increasing treatment times is the body is responding to the longer UV wave lengths and trying to protect itself from the cancer producing rays.

The shorter 254 rays lack the ability to penetrate and are not the harmful rays one associates with the term "ultraviolet".
