A tumor of 120 g absorbs a total of 1.7 J of energy. Determine the absorbed dose in rads.
I have no idea, any help is greatly appreciated!
To determine the absorbed dose in rads, we need to use the formula:
Absorbed Dose (in rads) = Energy absorbed (in joules) / Mass (in grams)
In this case, the energy absorbed is given as 1.7 J and the mass is given as 120 g. Substituting these values into the formula, we can calculate the absorbed dose:
Absorbed Dose = 1.7 J / 120 g
Now, we can simplify the calculation:
Absorbed Dose = 0.0142 J/g
Therefore, the absorbed dose is approximately 0.0142 J/g.
To determine the absorbed dose in rads, we need to use the formula:
Absorbed Dose (rad) = Energy Absorbed (J) / Mass (g)
Given:
Energy Absorbed = 1.7 J
Mass = 120 g
We can substitute the given values into the formula:
Absorbed Dose (rad) = 1.7 J / 120 g
Divide the energy absorbed by the mass:
Absorbed Dose (rad) = 0.0141667 J/g
Therefore, the absorbed dose in rads is approximately 0.0141667 J/g.
