A70-kg researcher absorbs 4.5 x 10^8 neutrons in a workday, each of energy 1.2 mev. the relative biological effectiveness (rbe) for these neutrons is 10. what is the equivalent dosage of the radiation exposure for this researcher, in millirem?

effective dose is 1.2 mrem

Explanation:

given data

mass m = 70 kg

absorb  n = 4.5 ×  

energy = 1.2 MeV

neutrons = 10

to find out

equivalent dosage

solution

we know here total energy in a day is

total energy = 4.5 ×   × 1.2

total energy = 5.4 × eV

and total energy = 5.4 ×  × 1.6 ×

so total energy = 8.64 × J

and for mass 70 kg

it will be = 8.64 ×  / 70

= 1.23 × rad

so

effective dose is here = 1.23 × × 10 = 0.0012 rem

so effective dose is 1.2 mrem

he made 11 calls in one day

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
