Radiation Background Studies for 0$ ubetabeta$ decay in $^{124}$Sn

Radiation background studies pertaining to $0 ubetabeta$ decay in $^{124}$Sn have been carried out. A TiLES setup has been installed at TIFR for this purpose. Neutron-induced background is studied in the TIN.TIN detector materials using fast neutron activation technique. The neutron flux ($E_nleq15$ MeV) resulting from SF and ($alpha, n$) interactions for the rock in the INO cavern is estimated using MC simulations. A two layer composite shield of borated paraffin (20 cm) + Pb (5 cm) is proposed for the reduction of neutron flux.
