The Solar System has entered a region of space where the laws of nature are slightly different. It will experience different physics for 3 years, then things will return to what we know now.

Which of the following decay chains will have the least impact on earth's biology during those 3 years?

1. $^{75}\text{As} \rightarrow ^{75}\text{Se} + \text e^- + \overline{v}_e : \lambda = 12d$

2. $^{74}\text{Ge} \rightarrow ^{74}\text{As} + \text e^- + \overline{v}_e : \lambda = 12d$

Try to include

• which organisms or ecosystems will be negatively impacted,

• with references to a clinical information source,

• and the best possible estimate for when negative effects will become apparent.

(Only one of these changes has occurred alone; all other physics remains unchanged)
