Chapter 19, Problem 19.79QP

Interpretation Introduction

Interpretation:

Reason for food when irradiated does not become radioactive have to be identified.

Concept Introduction:

• ${}^{10}B$ has the ability to capture slow neurons. In boron neutron capture therapy, tumor cells preferentially take up a boron compound and irradiated by a slow neutrons. Thus kills the cells through the energetic ${}^{10}B$ gives ${}^{7}Li$. The reaction is given below,

${}_5^{10}B+{}_0^{1}n\to {}_3^{7}Li+{}_2^4\alpha$

• Food exposed to high levels of radiation to kill insects and harmful bacteria.
