UVA radiation is the least intense, but it penetrates deep into the skin and causes long-term skin damage. It is associated with aging and can increase the risk of skin cancer. A study by the Skin Cancer Foundation indicates that UVA rays account for up to 95% of the UV radiation reaching the earth. This type of radiation is present during all hours of daylight and can lead to significant adverse health effects, such as photoaging and immune suppression.
2. UVB Radiation:
UVB radiation has a higher energy level than UVA radiation. It primarily affects the outer layer of the skin and is responsible for sunburn. While less prevalent than UVA rays, UVB rays play a significant role in developing skin cancers. According to the American Academy of Dermatology, UVB rays are most intense during midday and can cause direct DNA damage to skin cells. Proper protection, such as UV-blocking apparel, is necessary for welders to minimize exposure.
3. UVC Radiation:
UVC radiation is the most energetic and potentially harmful type of UV radiation. However, it is largely absorbed by the ozone layer and does not reach the earth’s surface. In welding, UVC can be generated by artificial sources, particularly from arc welding processes. The CDC warns that short exposures can cause severe eye damage and skin burns, known as “welders’ flash” or solar keratitis. Protective measures, such as appropriate eye protection and face shields, are essential for welders working in environments relevant to UVC exposure.
In conclusion, welders should understand the risks of all three types of UV radiation and take preventive actions to protect their skin and eyes from harmful effects.
