A mixture of radioactive substances gives off three types of radiation

1.	A mixture of radioactive substances gives off three types of radiations. (i) Name the radiations which are charged. (ii) Name the radiation similar in nature to cathode rays. (iii) Name the radiation similar in nature to X-rays. (iv) Name the radiation which is deviated most in a magnetic field. (v) Name the radiation which is not affected by an electric field.(vi) Name the radiation which has the maximum penetrating power. (vii) Name the radiation which has the highest ionising power. (viii) Name the radiation which has the highest speed. (ix) Name the radiation which when becomes neutral, become the atom of a rare gas.
Answer» (i) Alpha and beta radiations are charged. (ii) Beta radiation is similar in nature to cathode rays. (iii) Gamma radiation is similar in nature to X-rays. (iv) Beta radiation is deviated most in a magnetic field. (v) Gamma radiation is not affected by an electric field. (vi) Gamma radiation has the maximum penetrating power. (vii) Alpha radiation has the highest ionising power. (viii) Gamma radiation has the highest speed. (ix) Alpha radiation when become neutral become the atom of rare (helium) gas.
