Cause And Effect Essay On Eye Safety

Some eye injuries occur swiftly and catastrophically such as when a high-speed cutting wheel explodes and punctures an unprotected eye with a flying fragment. Most sensible people understand the need for eye protection from these kinds of dangers. On the other hand, some types of eye damage, such as cataracts, require years and possibly decades before they're even noticed.

It's human nature to devalue long-term hazards because a problem that occurs years or decades in the future is too remote to feel like a threat. This is one reason why many people approaching retirement age lack sufficient retirement funds, for example.

Cataracts are a remote threat that even professionals, who should know better, fail to protect against. Highly trained and educated doctors, researchers, and technicians are guilty of not wearing eye protection when working with x-ray machines. It's easy to forgo and even

If the radiation exposure of a procedure is already within a "safe" threshold, the ALARA principle states it should be reduced further if it's reasonably achievable. There are three ways of reducing exposure:

Reduce exposure time. Total received dosage is equal to the average dose rate times the exposure time. Therefore, reducing exposure time reduces the total dosage. Since radiation damage to human tissue is cumulative, less exposure means less potentially harmful damage.
Increase distance from the radiation source. Like all electromagnetic waves, x-ray intensity reduces by the square of the distance from the source. For example, tripling your distance reduces your exposure by a factor of nine. Medical professionals, should increase their distance from an x-ray device with leakage and from the source of x-ray scatter, which is typically the
