Problem solving (follow the GRESA format)

1. If the OER of an unknown radiation is 5.73 to cause stelirity using unknown radiation of about 485 Gy in anoxic condition what should be the intensity of the radiation to produce an effect of an aerobic condition?

2. An x-ray has a rate 480.50 mrad/hr that is used for radiographic imaging , if the duration of the imaging last for 5mins. What is the dosage received by the man?

3. A worker in a nuclear plant receives a 25 mrem at a distance of 45m from the radiation source. If he tripled his distance, what is the amount of radiation he would receive?

4. The death of a frog when irradiated with 200 kVp x rays should have an absorbed dosed of about 620 rad. If a test radiation is used to irradiate a frog and produce death when the absorbed dose is 300 red , what is the RBE of the said test radiation?​

Answer 1

Answer:

\frac{4}{2} \frac{3}{7} \\ \\ \frac{5}{ -3} \frac{ -2}{1} \\ \\ \frac{3}{1} \frac{ -1}{4} \\ \\ \frac{5}{ -7} \frac{3}{ -4} \\ \\ \frac{ -11}{ -10} \frac{3}{4} \\ \\
