Chapter 5

What is the wavelength (in \(\mathrm{mm}\) ) of light if its frequency is \(1.55 \times 10^{10} \mathrm{~s}^{-1}\) ?

Calculate the frequency of radiation if its wavelength is \(988 \mathrm{~nm}\). Where does this radiation appear in the electromagnetic spectrum?

You are exposed to radiation that has a wavelength of \(50 \mu \mathrm{m}\). What is the frequency of this radiation? Where does this radiation appear? Is this radiation ionizing or nonionizing?

How can you alter a house that tests over the \(4 \mathrm{pCi}\) level for radon?

Give one crazy application of x-ray science.

Which is the heaviest form of radiation: alpha, beta, or gamma?

Which is the heaviest form of radiation: alpha, beta, or gamma?

Fatman (Nagasaki bomb) used approximately \(6.4 \mathrm{~kg}\) of Pu-239. This artificially produced isotope \(\left(\mathrm{t}_{1 / 2}=24,100\right.\) years) undergoes alpha decay. How many kg and pounds would remain after three decay processes?

The \(t_{1 / 2}\) of As-74 is 18 days, how much of a \(160 \mathrm{mg}\) sample remains after 2160 hours?

Write a balance reaction for the decay Ir-192. This isotope undergoes alpha and gamma emission at the same time.

Bi-214 can decay to form T1-210. Write balanced reaction for this emission process.

When focused from the outside of the body, which type(s) of radiation penetrate(s) the body completely? gamma, proton, x-ray, alpha, or beta?
