Write a note on the following :
(a) Radio active wastes
(b) Joii.t forest management.

Explanation

(a) Radioactive wastes.
Radioactive wastes-use of nuclear energy has 2 serious inherent problems-accidental leakage (Three Mili Island and Chernobyl incidents) and safe disposal of radioactive wastes.
Radioactive wastes are damaging organismn, causing mutations at high rate, high doses radiation lethal, lower doses creates disorders like cancer. Extremely potent pollutant-has to be dealt with caution.
Storage of Nuclear wastes after pre treatment should be done in suitably shielded containers buried deep within rocks 500 m deep below the earth surface.
Detailed Answer:
(a) Radioactive Wastes : Radioactive wastes are generated during the process of generating nuclear energy from radioactive materials. Nuclear waste is rich in radioactive material that generates large quantities of ionizing radiations such as gamma rays. These rays cause mutation in organisms, which often results in skin cancer. At high dosage, these rays can be lethal. Safe disposal of radioactive wastes is a big challenge. It is recommended that nuclear wastes should be stored aller pre-trealinent in suilable conlainers, which should then be buried in rocks.
