original: Although alpha, beta, and gamma are most common, other types of decay were eventually discovered.
simplifications: Alpha, beta, and gamma are most common, but other decays were also found. Although alpha, beta, and gamma are common, other decay was found. More types of decay exist other than alpha, beta, and gamma. Alpha, beta, and gamma are most common. However, other types of decay were later discovered. Although alpha, beta, and gamma decay are most common, other types were later discovered. Alpha, beta, and gamma decay are the most, but other types of decay have been found. Although alpha, beta, and gamma are most common, other types of decay were eventually discovered. Although alpha, beta and gamma are typical, other radioactive decay were discovered. Alpha, beta, and gamma are most common, but other types of decay have been discovered. Even though alpha, beta, and gamma are the most common, other types of decay have eventually been discovered.
