Answer to Problem 40R
Alpha particle radiation is emitted in uranium-238 to thorium-234 transmutation.
Explanation of Solution
Introduction:
The process of decaying a nucleus and emitting radiation and energy is called radioactivity. It emits mainly three types of radiations; alpha, beta and gamma radiations which are associated with energy change.
Uranium-238 to thorium-234 transmutation can be written as:
As it is shown above, unstable parent nucleus
Conclusion:
Thus, alpha particle radiation is emitted in uranium-238 to thorium-234 transmutation.
(b)
To identify: The type of nuclear radiation emitted in given transmutation.

Answer to Problem 40R
Beta particle radiation is emitted in boron-12 to carbon-12 transmutation.
Explanation of Solution
Introduction:
The process of decaying a nucleus and emitting radiation and energy is called radioactivity. It emits mainly three types of radiations; alpha, beta and gamma radiations which are associated with energy change.
Boron-12 to carbon-12 transmutation can be written as:
As it is shown above, unstable parent nucleus
Conclusion:
Thus, beta particle radiation is emitted in boron-12 to carbon-12 transmutation.
(c)
To identify: The type of nuclear radiation emitted in given transmutation.

Answer to Problem 40R
No radiation emitted in cesium-130 to cesium-130 transmutation.
Explanation of Solution
Introduction:
The process of decaying a nucleus and emitting radiation and energy is called radioactivity. It emits mainly three types of radiations; alpha, beta and gamma radiations which are associated with energy change.
Cesium-130 to cesium-130 transmutation can be written as:
As it is shown above, no change in cesium before and after transmutation hence no radiation emitted.
Conclusion:
Thus, no radiation emitted in cesium-130 to cesium-130 transmutation.
(d)
To identify: The type of nuclear radiation emitted in given transmutation.

Answer to Problem 40R
Alpha particle radiation is emitted in radium-226 to radon-222 transmutation.
Explanation of Solution
Introduction:
The process of decaying a nucleus and emitting radiation and energy is called radioactivity. It emits mainly three types of radiations; alpha, beta and gamma radiations which are associated with energy change.
Radium-226 to radon-222 transmutation can be written as:
As it is shown above, unstable parent nucleus
Conclusion:
Thus, alpha particle radiation is emitted in radium-226 to radon-222 transmutation.
