Final answer:
The effective dose can be determined using the ICRP 26 / 30 methodology. The effective dose takes into account the type and energy of the radiation, as well as the sensitivity of different organs and tissues. To calculate the effective dose, we need to know the absorbed dose and the quality factor (QF) of the radiation.
Step-by-step explanation:
The effective dose can be determined using the ICRP 26 / 30 methodology. The effective dose is a measure of the overall harm caused by radiation exposure to different organs and tissues of the body. It takes into account the type and energy of the radiation, as well as the sensitivity of different organs and tissues.
To calculate the effective dose, we need to know the absorbed dose and the quality factor (QF) of the radiation. The absorbed dose is the amount of energy absorbed per unit mass by the body tissue. In this case, the person ingests 5 µCi of 1-125. One curie (Ci) is equal to 3.7 x 10^10 disintegrations per second and 1 µCi is equal to 3.7 x 10^4 disintegrations per second.
Since the person ingests 5 µCi, we can calculate the number of disintegrations per second by multiplying 5 µCi by 3.7 x 10^4 disintegrations per second/µCi. This gives us the total number of disintegrations per second. To find the absorbed dose, we need to multiply the number of disintegrations per second by the energy of each disintegration (in Joules) and divide by the mass of the person (in kg).
Once we have the absorbed dose, we can calculate the effective dose by multiplying the absorbed dose by the QF for the specific type of radiation. The QF for 1-125 is 1. This gives us the effective dose in sieverts (Sv).
