The intensity of the Sun is directly related to it's height in the sky.
Mid- Day is therefore the most dangerous time.
In Indiana, on the far far west of EDT zone, mid-day does not occur until around 1:50pm. You can figure mid-day locally by taking the halfway point between sunrise and sunset at your location. Should be about 1pm most places on DST, and around noon when on Standard time.
I try to avoid the sun from 12 noon -3:40pm in the spring-summer months. I never burn if I follow this plan, and I am very fair skinned.

The most dangerous times for sun exposure are typically between 10am and 4pm when the sun's rays are the strongest. It is important to seek shade during these hours and wear protective clothing and sunscreen to minimize the risk of sun damage.
Long term exposure can be dangerous.
The UV exposure is dangerous because it penetrates the skin. Visible rays do not.
UVB rays are more dangerous and damaging. there are many different category of rays which are harmful for human and extent of harm depends upon the extent of exposure. X rays if exposed for longer time may be dangerous.UV rays during experimentation is exposed more by the students so care must be taken.
No Rays can not be dangerous because people mistake them for rays and think that they are very dangerous and start to panic, so no, Rays are not dangerous to our enviormental oceans!:)
X-rays are only possibly dangerous to the person being x-rayed. The possible danger from the x-rays CAN'T be passed on.
gamma rays
The way to stop being damaged by exposure to x-rays is to reduce or eliminate your exposure to x-rays from man-made sources. There is little you can do about naturally occurring x-rays.
Cosmic rays can be extremely dangerous, and exposure to them can cause genetic mutations, cancer, radiation posion, and death. Luckily, life on Earth is largely protected from these harmful effects by the Earth's atmosphere (which stops all cosmic rays with energies below 1 GeV) and the Earth's magnetic field (which deflects cosmic rays).
Externally, gamma radiation is dangerous because it can penetrate the body. Alpha is most dangerous if ingested.
There is a risk of getting radiation exposure from x rays. This exposure can increase the risk of gene mutations and cancer. Overall, x rays are safe for young children, but should avoid over exposure and unnecessary exposure when able.
ultra-violet rays cause skin cancerMost times, it is caused by excessive sun exposure.
Scotch tape only produces x-rays in a vaccum, which would be more harmful to you than the x-rays. However, the "dangerous" part is in the length of exposure to any type of ray, as well as the strength. Short answer- dont repeatedly pull off scotch tape while in a vaccum for long periods of time.
