The given information is not sufficient to determine the radionuclide. However, we can use the formula for half-life, t1/2 = ln(2)/λ, where λ is the decay constant. Using the given decay rate, we can find λ = 0.0226 min^-1. Plugging this into the formula, we get t1/2 = ln(2)/0.0226 = 30.9 min, which corresponds to choice B.
