What is the SI unit for radiation dose? What is its value in J/kg and rad?
In a laboratory accident, a work area is contaminated with radioactive material. Health physicists monitor the area during a 30-day period and obtain the data shown in the table. The accident occurred at time t = 0 days. They determine that it will not be safe for workers to enter the area until the radioactivity level has dropped to 16 counts per minute. Of the choices listed, which one is the earliest time after the accident that workers could safely return?

- The SI unit of radiation dose is "gray" (Gy) which is radiation equivalent to 1 J/kg. A small energy delivered as ionizing radiation can create huge damage at the cellular level, and the sievert is a unit of the health effect of radiation proportional to the radiation dose, but multiplied by factors allowing for the absorption and the nature of the radiation. Which of these statements are true? You may need to research these answers, but they are useful to know. The background radiation flying in a commercial aircraft is about 10x the average natural background at the surface of Earth. A dose of 4 to 5 sieverts will kill a human with a 50% probability within 30 days if the dose is received over a short period (say accidental exposure). The dosage from a dental X-ray is about 1 milli-sievert. NASA astronauts are allowed to receive a dose of 1 sievert during their career.
