9:13 PM Sun 21 Apr 51% . " 2018-2019 ACTIVITY-RADIATION PHYSICS 104 Q6:An air sample is contaminated with 150, which has a half-life of 2.03 min. One possible way to minimize its hazard is to pass it through a long pipe to allow it to decay inside the pipe until it can be safely released into the atmosphere. If the oxygen moves at a constant speed of 1.1 m/s in the pipe, how long must the pipe be for the...
IONISING RADIATION QUESTION 2 The risk for stochastic effects when a person receives a non-whole body dose can be described by: Select one: a. The activity. b. The absorbed dose. c. The effective dose. d. The equivalent dose. The effective dose from an x-ray point source is measured to be D mSv. If the distance to the source is doubled and the exposure time is halved, what is the new effective dose? Select one: a. D mSv b. D/2 mSv...

hole-body scan? the same total amount of energy to the body of 75 kg person as one w (Number of chest x rays - 600) Q10:(+)) А 67 kg person accidently ingests 0.35 Ci of tritum (t1/2 3.88 x 10%). Assume that the tritium spreads uniformly throughout the body and that each decay leads on the average to the absorption of 5.0 keV of energy from the electrons (RBE-1) emitted in the decay. Calculate A. the initial number of...

Technetium Dosage. Radioactive isotopes are often used for medical imaging. Technetium-99m (Tc-99m) is a particularly popular isotope since it has a short half-life and is easy to make. Also, Tc-99m can be chemically bonded to a number of different compounds and cell types for imaging different parts of the body. Tc-99m has a half-life of 6.02 hours. It decays into Tc-99 by emitting a gamma ray of energy 140 keV. For this problem, assume that Tc-99m is present in the...
