Why does the UV rays of the sun change during the day?Due to the sun’s elongated rays and lower atmospheric opacity during the summer, UV radiation is at its highest level. As a result of the sun’s lower angular position and the longer path its rays take through the atmosphere during the winter, more UV radiation is absorbed, resulting in lower UV levels.
What are the times when the UV rays of the sun are most dangerous in NZ?the most dangerous time of the uv rays is during daylight saving months which is (september to april) at around 10am to 4pm
What affects UV radiation?Numerous variables, such as the time of day, season, cloud cover, altitude, location, and nearby surfaces, have an impact on the UV level.
What is the UVNZ app? Forecasts of the UV index (UVI) are provided by the app for various places in Aotearoa. Skin damage is possible if the UVI is 3 or above, thus protection is necessary. The app uses information from NIWA Taihoro Nukurangi to tell you when, based on your location, you should use sunscreen.
What different types of radiation does the sun send out? Radiation is one way to transfer heat to visible light
What is UVB and UVA and UVC? UVB is radiation that gets to the top layer of your skin and can cause sunburn ,UVA is radiation that goes deep into the skin. It can cause long-term damage like wrinkles, blotchiness, sagging and skin cancer and UVC is the most radiation.
Which is the most dangerous and why? All UVC is absorbed by ozone and oxygen in the earth’s atmosphere, preventing it from reaching the surface. Workers must safeguard themselves from additional UVC sources, such as arc welding, which can occur.
Is UV exposure good for our health?Premature ageing and skin cancer are side consequences of continuous UV exposure, but sunburn is a sign of short-term overexposure. If eye protection is not worn, exposure to UV raises the risk of potentially blinding eye illnesses. Overexposure to UV light can cause major health problems, including cancer.
What happens when you have too little UV Exposure?Exposure to UV rays can cause premature ageing of the skin and signs of sun damage such as wrinkles, leathery skin, liver spots, actinic keratosis, and solar elastosis.
