My question is:
What is the frequency and wavelength of a 50 meV gamma-ray photon?
How do I find it?
Lamp power (W)
How much lamp power is required for 99.9% disinfection of Giardia cysts (K = 2.4 cm?/mJ) in a
typical household water supply stream of 5.0 USGPM, through a typical % supply line? The
supply line has an 8.0 cm-long transparent acrylic pipe segment for exposure to the UV light.
Assuming that 10.0% of a 100 W light bulb's energy output is in the visible range (typical for incandescent bulbs) with an average wavelength of 580 nm, and that the photons spread out uniformly and are not absorbed by the atmosphere, how far away
(in km) would you be if 446 photons per second enter the 3.10 mm diameter pupil of your eye? (This number easily stimulates the retina.)

- Ultraviolet (UV) radiation is a part of the electromagnetic spectrum that reaches the Earth from the Sun. It has wave-lengths shorter than those of visible light, making it invisible to the naked eye. These wavelengths are classified as UVA, UVB, or UVC, with UVA the longest of the three at 320 nm to 400 nm. Both the U.S. Department of Health and Human Services and the World Health Organization have identified UV as a proven human carcinogen. Many experts believe that, especially for fair-skinned people, UV radiation frequently plays a key role in melanoma, the deadliest form of skin cancer, which kills more than 8000 Americans each year. UVB has a wave-length between 280 nm and 320 nm.

New research is showing that ultra-violet is not the only type of radiation from the sun that can increase the risk of skin cancer. Rates of skin cancer among pilots are twice that of non-pilots, but the glass used in planes blocks most the ultra-violet radiation. Pilots are also exposed to x-rays from the sun during flight. The x-rays that pilots are exposed to in one day of work are equivalent to a chest x-ray. Although getting an x-ray for medical reasons is believed to be safe, researchers believe that the frequent exposer that pilots experience increases their risk for skin cancer.
