How can i access the Target script from the Explode function? This does not work for me

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class Grenade : MonoBehaviour { float timer = 2; float countdown; float radius = 20; float force = 2000;
bool hasExploded;

 public bool takeDamage = false;

 [SerializeField] GameObject explosionParticles;

  
 // Start is called before the first frame update
 void Start()
 {        
     countdown = timer;
 }

 // Update is called once per frame
 void Update()
 {
     countdown -= Time.deltaTime;
    
 }

 private void OnTriggerEnter(Collider other)
 {
     if(other.tag == "Enemy" || other.tag == "Floor")
     {
         if (countdown <= 0 && !hasExploded)
         {
             Explode();             
         }
     }
 }

 void Explode()
 {
     GameObject spawnedParticle = Instantiate(explosionParticles, transform.position, transform.rotation);
     Destroy(spawnedParticle, 1);
     

     Collider[] colliders = Physics.OverlapSphere(transform.position, radius);  // Find objects with colliders within the radius 
     foreach (Collider nearbyObject in colliders)
     {
         Rigidbody rb = nearbyObject.GetComponent<Rigidbody>();      

         if (rb != null)
         {               
             rb.AddExplosionForce(force, transform.position, radius);
         }
         **Target targetScript = nearbyObject.GetComponent<Target>();
         if(targetScript != null)
         {
             targetScript.Health = targetScript.Health - 10; 
         }**
            
     }

     hasExploded = true;
     Destroy(gameObject); 
 }

 

}
