214Po - 4particles = 210Pb. Alpha particles are rubbish at ionising and are stopped by 5 cm of air, you could protect yourself with paper lol

When an Alpha particle ejected from within the nucleus the mother element loss two units of atomic number and four units of mass number. Thus the mass number of new elements is 210 and atomic number of Points is 84 change to 82 that is lead.
