एक रेडियोधर्मी तत्त्व का क्षयांक 'λ' 0.00231 प्रतिदिन है। इसका अर्द्ध-आयुकाल (दिनों में) और औसत आयुकाल (दिनों में) क्रमशः है :


Options:

  1. 300, 432.9
  2. 432.9, 300
  3. 333.3, 400
  4. 400, 333.3

Right Answer: 300, 432.9

अर्द्ध-आयुकाल (Half-life period) T½ = 0.693/λ = 0.693/0.00231 = 300 दिन। औसत आयुकाल (Average life period) τ = 1/λ = 1/0.00231 ≈ 432.9 दिन। इसलिए सही विकल्प 300 और 432.9 है।
