  Ultra High Cosmic Rays) made by He-like lightest nuclei might fit clustering
along Cen A. Moreover He like UHECR nuclei explain Virgo absence because the
light nuclei fragility and opacity above a few Mpc. We foresaw (2009) that
UHECR He from Cen-A AGN being fragile should partially fragment into
secondaries at tens EeV multiplet (D,He^{3},p) as the recent twin multiplet
discovered ones (AUGER-ICRC-2011), at 20 EeV along Cen A UHECR clustering. We
suggest that UHECR are also heavy radioactive galactic nuclei as Ni^{56},
Ni^{57} and Co^{57} widely bent (tens degree up to 100 degrees) by galactic
fields. UHECR radioactivity and decay in flight at hundreds keV is boosted (by
huge Lorentz factor (billion) leading to PeVs electrons and consequent
synchrotron TeVs gamma offering UHECR-TeV correlated sky anisotropy. Electron
and tau neutrinos secondaries at PeVs maybe the first signature of such
expected radioactive secondary tail.
