Why are government recommendations about radiation exposure made on an amount-per-year scale?

They aren't always. There are exposure limits for other time periods as well. Brazil, for example, has a 5-year limit of exposure (which is only twice the 1-year limit of exposure), and often workers around nuclear reactors have guidelines for shorter periods in addition to the yearly ones. The issue is that radiation damage is cumulative. A single medical X-ray is not likely to cause any significant adverse effects. However, the technician goes and hides behind a lead shield, because while you might have one or two a year, he's sitting there with the thing two hundred and fifty days a year, multiple X-rays per day. Basically, the body can recover from a single moderate dose better than from a continuous lower dose.

What is radiation exposure safety?
Radiation exposure safety is the process of preventing or minimizing exposure to radiation, and tracking what does occur.
Radiation symtoms can result from a single exposure and are contagious?
While radiation symptoms can occur from a single, prolonged, exposure, the symptoms of radiation are not contagious.
What is another name for radiation exposure badges?
Badges used to measure exposure to ionizing radiation are usually called radiation dosimeter badges.
What are the risks of nuclear radiation?
The exposure to nuclear radiation has many risks associated with it. Cancer, DNA mutations, and radiation poisoning can all occur with any level of radiation exposure.
Can your baby die of radiation exposure?
Yes. Depending on the length of the exposure, radiation can sicken or kill any human.
Identify THREE reasons a person may develope radiation sickness?

What are 3 reasons radiation sickness varies?
Radiation sickness varies depending upon duration of exposure, whether it was an internal or external exposure, and the dosage of radiation.

Is there an infrared radiation exposure statement out there by some organization?
Infrared radiation is generally known as "heat", so the statement "Don't touch the stove!" would qualify as a "radiation exposure statement".

How do radiation technicians know when they have been over exposed by radiation?
Radiation personnel wear a small badge containing a film which darkens upon exposure to radiation. These are regularly screened to determine if a dangerous exposure has taken place.
